NASA DIGITAL ENGINEERING ACQUISITION FRAMEWORK

HANDBOOK

1. SCOPE

1.1 Purpose

This NASA Technical Handbook provides guidance for establishing NASA’s digital engineering

acquisition framework that includes Data Requirements Descriptions (DRDs) and contractual

language for the Statement of Work (SOW) in support of a digital engineering environment

(DEE).

A DEE will modernize how the Agency conceptualizes, designs, develops, delivers, operates,

and sustains systems. A DEE will help enable collaborative digital engineering while integrating

stakeholders with authoritative decentralized sources of data and models seamlessly across

organizations and disciplines supporting life-cycle activities from concept through disposal.

Digital engineering is the integrated digital approach that utilizes authoritative sources for

product and system data and associated models collaboratively across all product-involved

disciplines supporting life-cycle activities from conceptualization through disposal (Pre-Phase A

through F). A DEE enables the interconnected data, people, processes, and technology used to

store, access, analyze, and visualize evolving systems' data and models to address the needs of

enterprise-wide stakeholders. It provides information referencing topics such as model-based

definitions (MBD) (annotated 3D CAD models), model-based analyses (MBA), model-based

systems engineering (MBSE), model-based enterprise (MBE) (aiding manufacturers to integrate

system, service, product, process, and logistics models across the manufacturing/support

enterprise), product data and life-cycle management (PDLM), and general guidance to adapt the

methods needed to implement digital engineering product/data acquisition requirements

maximizing model representations. This NASA Technical Handbook supersedes NASA-HDBK-

0008, NASA Product Data and Life-Cycle Management (PDLM) Handbook.

A process for management of technical data is required by NASA Procedural Requirements

(NPR) 7123.1, NASA Systems Engineering Processes and Requirements, for ensuring that the

data required are captured and stored, data integrity is maintained, and data are disseminated as

required. A digital engineering acquisition framework requires that information technology (IT)

systems across NASA be made interoperable or federated to the extent needed to provide a

secure, readily accessible environment to enable required collaborative digital engineering

capabilities. This framework augments PDLM and addresses the acquisition, retrieval, usage,

and storage of all program/project data in addition to the technical data used in the life cycle of a

system.

Implementing a digital, model-based acquisition framework negates much of the traditional

document-centric approach in lieu of a digital engineering environment where digital models

hold the information once housed in documents to meet the program/project’s decision or

information needs in addition to supporting the product-related activities. To achieve the highest

level of collaboration, interoperability, efficiency, and data availability, the implementation of a

fully digital model-based acquisition framework environment is necessary. A model-based

acquisition framework is intended to increase the probability of mission success by increasing

the availability, effectiveness, and efficiency of data interchange and integration across like as

well as disparate systems for availability of the right data to the right people at the right time,

thereby enabling the right decisions and reducing risk.

1.2 Applicability

This NASA Technical Handbook is applicable to the complete program/project life cycle of

current and future NASA space flight single-project and tightly coupled programs and their

projects as defined in NPR 7120.5, NASA Space Flight Program and Project Management

Requirements, and is recommended as guidance in all other programs/projects. The example

DRDs in this NASA Technical Handbook should be modified to meet each program/project’s

and product’s needs.

This NASA Technical Handbook is approved for use by NASA Headquarters and NASA Centers

and Facilities. It may also apply to the Jet Propulsion Laboratory (JPL) (a Federally Funded

Research and Development Center [FFRDC]), other contractors, recipients of grants and cooperative

agreements, and parties to other agreements only to the extent specified or referenced in their

applicable contracts, grants, or agreements.

This NASA Technical Handbook, or portions thereof, may be cited in contract, program, and

Related Documentation Practices.”

NOTE to STD-AD

Functional Configuration Audit and Physical Configuration Audit (FCA/PCA)

Documentation

Sample Statement of Work Words (*See SOW Tailoring Note below.)

Functional Configuration Audit (FCA) and Physical Configuration Audit (PCA): FCA/PCA

shall be conducted in accordance with the requirements specified in SAE/EIA-649-2. The data

required to support the FCA and PCA shall be provided as defined in DRD No. STD-AD.

The Contractor shall provide the facilities and administrative support necessary for the audits.

The requirements for the necessary support are defined in SAE/EIA-649-2 and as follows: (1)

provide support for maintaining a system for recording, processing, tracking, and reporting the

status of all findings (FCA/PCA Action Items) identified during the audit, corrective action, and

closeout status; and (2) provide facilities and administrative support to the audit team(s).

*SOW Tailoring Note

Tailoring of SOW Words to Include Contractor Self-assessment FCA/PCA: (Although the

Government normally conducts and approves the FCA/PCA, it may be beneficial to the

Government to limit personnel involvement in the detailed reviews and delegate to the

Contractor additional responsibility for the conduct of the FCA/PCA on a project-by-project

basis. It is incumbent upon the NASA Project Manager and the Project CDM representative to

assure that the project-specific additional responsibility is tailored into the SOW and that DRD

No. STD-AD is tailored to reflect the additional documentation to be supplied.)

Application Data: FCA/PCA audits certify that configuration items (CIs/CSCIs) meet criteria for

establishing the Product Baseline as defined in SAE/EIA-649-2. The FCA/PCA may be included

within the scope of the Systems Acceptance Review so long as specific FCA/PCA certifications

are obtained.

A.14 CONTRACT LANGUAGE FOR DATA ACQUISITION AND

INTEROPERABILITY

A.14.1 Data Acquisition

This section provides guidance for ensuring that NASA provides data acquisition requirements to

enable the reference and reuse of data through a program/project’s full life cycle.

Data acquisition requirements should be initially presented during Requests for Proposal

(RFP)/Request for Quote (RFQ) development to establish integrated data architecture for a

program/project’s information systems architecture, data architecture, and information systems

capability roadmap. The ability to meet data interoperability requirements should be a part of the

contract performance metrics on which the Contractor has to report and be evaluated throughout

contract execution. This recommended contract language should be applied to the Center’s data

procurement documents.

The following contract language is categorized based on the type of data interoperability being

performed. Also included is contract language pertaining to metadata and data transmittal:

a. Proprietary Formatted Data includes data that is generated on a commercial off-the-

shelf (COTS) or custom-built application where the application’s data format is proprietary to

those systems. The Contractor should provide or deliver the following:

(1) A definition of the application and version that produced the file.

(2) The native proprietary file itself.

(3) A commonly readable representation of the file (Joint Photographic Experts

Group [JPEG, JPG], Graphics Interchange Format [GIF], Portable Network

Graphics [PNG], or machine-readable Portable Document Format/Archivable

[PDF/A]).

(4) The application (source code and executable), with the concurrence of the NASA

Contracting Officer’s Representative, required to read the native file format for

file types where there is no commonly readable representation of the file.

(5) Object Management Group (OMG), 2D/3D formats, videos, neutral and/or 3D

PDF files.

b. Structured Digital Data from a Source Repository is digital data extraction from a

source data repository provided in a computer-readable format that maintains the referential

integrity of the data.

(1) The Contractor shall provide structured, computer-readable data, including all

relationships between data, in one of the following formats:

(2) Microsoft® Word® and Microsoft® Excel® files.

(3) Other commonly readable format (e.g. a text file (.txt), or rich text format (.rtf))

approved by NASA.

d. Metadata describes the contents of digital files. Metadata should be defined in a

computer-readable data format to support automation and facilitate data interoperability.

(1) Descriptive metadata describes an information resource for identification and

retrieval through elements such as title, author, and abstract.

(2) Structural metadata documents relationships within and among objects through

elements such as links to other components (e.g. how pages are put together to

form chapters).

MySQL is a relational database management system that runs as a server providing multi-user access to a number

of databases.

days prior to its first use.

e. Transmittal of data should be via one of the following options; the data transmission

method should be defined in each DRD and Statement of Work (SOW)/Performance Work

Statement (PWS):

(1) View data in Contractor systems should support viewing data within the

Contractor’s electronic system in a format readable by a standard NASA

workstation or otherwise approved by NASA. This action will be deemed as a

delivery of data in place, and such data will be maintained within the Contractor’s

system.

(2) Direct entry to NASA’s system should include direct user entry of data into a

NASA-owned system, including fields, values, or other information as required

by the NASA system.

Technology (NIST) 800 Series Publications and FIPS PUB 140-2, Security

Requirements for Cryptographic Modules, to meet data encryption

requirements.

f. Data Interoperability

This section provides recommended requirement language for guidance in defining data

interoperability via industry standards, information systems architecture, and data architecture

best practices. A tailored set of the following statements should be included as needed in RFPs

and planning documents:

(1) Data is an essential enabler and should be made visible, accessible, and

understandable to any potential user as early as possible in the program/project’s

life cycle to support project and mission objectives as constrained by security and

access needs.

(2) Data assets should be made visible by creating and associating metadata

(“tagging”), including, but not limited to, discovery metadata, for each asset.

(3) Developed metadata standards should comply with applicable national and

international consensus standards for metadata interoperability; all metadata

should be retrievable using the NASA Centers’ systems with requirements to

access the metadata.

(4) Data assets should be accessible by making data available in shared spaces; all

data assets should be accessible to all users at the NASA Center except where

limited by law, policy, or security classification.

(5) Data that is accessible to all users at the NASA Center should conform to that

Center’s specified data publication methods that are consistent with the Center’s

current and planned information systems capabilities.

(6) To enable trust, data assets should have associated information assurance and

security metadata and an identified authoritative Contractor and/or Center-level

source for the data.

(7) Data interoperability should be enabled through business and mission processes

reusing the Center’s information system capabilities.

(8) Semantic and structural agreements for data interoperability should be promoted

through communities consisting of data users (producers and consumers) and

system developers.

(9) Data interoperability concepts and practices should be incorporated into education

and awareness training and Center-level processes.

(10) Programs/projects should acquire the minimum essential Contractor-originated

data required to meet all program/project life-cycle requirements.

(11) Program/project managers and delegated Technical Authorities should consider

data requirements for future procurement needs in a manner that fosters

competitive procurement opportunities.

To allow for data interoperability, program/project managers and delegated Technical

Authorities should ensure that Contractor data delivered to authoritative sources are acquired

through the contract and that DRDs specify data to be delivered in specified digital data formats

in lieu of “Contractor format acceptable” or similar language:

(1) Contracts should specify the required delivered data transaction scope, data

delivery formats, metadata, naming standards, and data interoperability standards.

The definition of data formats and transaction sets should be independent of the

method of access or delivery.

(2) Regardless of the format of acquired data, the Contractor should mark any data

provided with less than unlimited rights with the appropriate legend as set forth in

FAR 52.227-14, Alternates II and III, Rights in Data—General.

(3) Contractors should obtain approval from the NASA Center for all proposed

contractual deviations from existing data standards and specifications.

Program/project managers and delegated Technical Authorities should ensure that data is

acquired with sufficient access and usage rights to support the full range of program/project

needs. This includes, but is not limited to, the following:

(1) The need for data to be used by organizations outside NASA (e.g. support

Contractors and companies bidding on new procurements).

(2) In instances when NASA acquires data with less than unlimited rights, the impact

to the full program/project is to be assessed.

(3) The Contracting Officer and the cognizant legal office should be consulted to

develop a strategy to mitigate any adverse impacts associated with the limited or

restricted data rights.

(4) Program/project managers and delegated Technical Authorities should include

language in the statement of work to address the marking of data (e.g. “The

Contractor should determine the data restriction that applies to each data

deliverable and mark or transmit the data restriction in accordance with section

X.X of the Data Procurement Document.”).

Incrementally define a:

(1) Common vocabulary to support each phase of the program/project life cycle as

exit criteria for a program/project life-cycle phase.

(2) Common program/project data dictionary to support each phase of the

program/project life cycle. This activity should be performed as program/project

phase exit criteria to support the startup of the next phase.

(3) Common namespace standards to support each phase of the program/project life

cycle as exit criteria for a program/project life-cycle phase.

If a NASA-/Center-level common vocabulary, common program/project data dictionary, or

common namespace standard exists, then the contract should ensure that developed solutions use

these common architecture elements.

1. Objective

The National Aeronautics and Space Administration (NASA) Office of the Chief Information

Officer (OCIO), led by the Technology and Innovation (T&I) Division, proposes data

requirements language for contracts intended to enable effective interaction and utilization of

contractor-generated data and information. Introduction of such requirements language ensures

that data acquisitions are appropriately included into NASA contracts, guaranteeing the

government does not lose data, information, or knowledge that has been produced during the

contract and, ultimately, lowering cost and effort for both parties. T&I proposes new contracts

that treat data as a valuable asset and structure data-related deliverables in formats that can be

shared, regardless of whether a determination has been made as to whether the data should be

made available to the public.

NASA should acquire the minimum, essential contractor-originated data required to meet all

program life-cycle requirements. Every attempt should be made to integrate all functional

specialties, e.g., safety, reliability, quality, logistics, test and verification, etc., to minimize data

acquisition redundancies and inconsistencies. This integrated effort must include sub-projects

within the various programs. The requirement to deliver and manage data in a digital

environment influences the manner in which data delivery requirements are levied on existing

and future contracts. Ongoing contracts should consider contract modifications to require the

delivery and management of contractually delivered data in a digital environment on contracts.

The purpose of this Appendix is to provide specific data requirements language to supplement

the existing FAR and NASA FAR Supplement (NFS) clauses. This document provides guidance,

templates and specific language to enable data integrity, and control and access during and after

the contract is awarded.

2. Background

Historically, NASA procurements have overall included very little, if any, data language in

contracts to provide the Government readily available access to information produced during

contract periods or when transferred after expiration of the period of performance (PoP). The

one exception is large programs, and even they have incurred large and often unexpected costs

when transferring data to the Government at contract end. This has forced NASA organizations

to negotiate with contractors on access during the contract period and the transfer of data at

contract end. This has resulted in higher overall costs because the Government essentially does

not benefit in tradition procurement terms by allowing the competition of bidders against each

other. When contractors turn over data at contract end, they often levy large data conversion

costs along with the transfer overheads making the cost of the process higher than expected.

Often, contractors will classify data as primarily proprietary or intellectual property during the

contract, making any negotiations tougher due to the difficulty of defining who really owns the

data. This puts the Government at a disadvantage when trying to negotiate after the contract has

been signed.

In an effort to compile the appropriate contract language to ensure data are protected throughout

the contract and transferred as required at contract end, the team met with both contractor and

civil servant subject matter experts (SMEs) from many previous and existing NASA Programs

and institutional and engineering/science organizations. The team summarized lessons learned

and documented significant risks and appropriate mitigations with the end goal of developing

draft language for consideration and use in future contracts. The draft language will have the

appropriate reviews with Legal, Procurement, and appropriate SMEs.

In this effort, the team reviewed and referred to a considerable amount of previously developed

white papers and documentation. The team also researched NASA wide for other material and

found a significant amount of information concerning data and information available from the

NASA Earth Science program. In addition, the NASA Earth Science program developed a Data

and Information Policy accessible at http://science.nasa.gov/earth-science/earth-science-

data/data-information-policy/, which provided the team valuable information and associated

contract language. The team reviewed and utilized language from the Earth Science program,

which promotes the full and open sharing of all data with the research and applications

communities, private industry, academia, and the general public. The greater the availability of

the data

, the more quickly and effectively the user communities can utilize the information to

address basic Earth science questions and provide the basis for developing innovative practical

applications to benefit the general public.

3. Lessons Learned

Given the advances in technology over recent decades, it becomes necessary to investigate new,

more efficient approaches and business practices to achieve reasonable governmental access to

data while simultaneously minimizing cost impacts associated with such requests.

Numerous lessoned learned were identified while looking into the Space Shuttle Program (SSP),

International Space Station (ISS), Launch Services Program (LSP), and various other contracts

associated with Commercial Crew, Constellation, Orion, and others. The primary lesson learned

was if one simply omits data requirements in a contract, access to the data during the contract

and at contract end would then become only attainable at additional cost. Inclusion of tailored,

template contract language can aide in this regard and ensure critical data access and integrity for

the lifespan of the particular record.

For purposes of this document, the term data will be used to cover data, information, and knowledge stored in an

information system.

The SSP had numerous issues associated with data over the 30-year program. Data media varied

from paper, to microfiche, to digital, making delivery, translation, and/or reuse a significant cost

and effort. Additionally, the SSP did not have the data stewardship to ensure that downstream

records management could be effectively and efficiently implemented. Security classifications

for much of the documentation were not considered at the beginning for items such as export

control—sensitive but unclassified (SBU), International Traffic in Arms Regulations (ITAR),

etc. As such, huge amounts of backlogged data could not be dispositioned.

The SSP design data and drawings were not contractual deliverables and, in most instances, were

further complicated by multiple designs for various systems being developed across the program.

This resulted in reference material not being available to multiple Centers across the program.

For the SSP, the resulting theme is the program neither defined nor added contract language to

obtain data at the end of the contract, resulting in millions of dollars spent researching and

obtaining data.

The ISS program continues to maintain multiple data systems for parts accounting, disposition,

management, etc., because not one of their current systems can provide all functionality required;

and the form of data does not lend itself to a single management system.

Both the SSP and ISS programs were stuck with huge balloon payments to purchase proprietary

code that was required to run and maintain software systems formerly contractor owned and run.

Without this code, the data would be unusable or require expensive conversion.

The ISS Payload Processing Contractor was asked at the end-of-contract to turn over SSP work

procedures at contract closeout. These work procedures were developed during the contract and

were to be turned over to the incoming contractor; however, the contractor deemed many of the

subject procedures to contain “trade secrets,” making them proprietary. As such, many of the

procedures developed during the life of the Payload Processing Contracts were never obtained

and/or turned over. Again, the foresight to identify data required at end-of-contract was never

considered at the beginning of the contract, or the contract specified the “best available data”

that, while seeming the most economic path, turned out proprietary.

The trend of moving from cost plus contracts to performance-based contracts, in many cases,

encouraged contractors to develop and use their own data systems while NASA counterparts

became further disengaged in day-to-day activities. This continuing trend to convert more

contracts to fixed price can further acerbate the issue of obtaining data as well as the possibility

of more intellectual property being owned by the contractor.

The LSP, with the contract strategy of fixed price contracts to further reduce contract cost, has

chosen to accept “existing contractor data” to the maximum extent possible. This strategy,

although seeming the most cost effective, may become costly in the event the Government has a

need to obtain the data at contract end or any time during the contract if specific contract

language does not address this data at the inception of the contract.

The Commercial Crew Program (Commercial Crew Development) is proceeding with very little

data deliverables resulting in only the interfaces or interface control documents (ICDs) available

and only available for describing identified interfaces such as known touch points and enabling

determination of safety assurance.

A recent OCIO contract has contract language stating “all Contractor-developed applications

shall be owned by NASA and fully transferable, including source code and documentation, to a

new vendor at the conclusion of contract.”

In summary, data standards vary across NASA programs from no standards to various attempts

to establish a standard. Most program managers in the past have had the perception that data will

cost a lot of money resulting in data not addressed in most contracts, or data deliverables were

removed during one of the many cost-cutting exercises. The most efficient and least expensive

method of obtaining data is to include achievable requirements in the RFP or front end of the

contract. Any end-of-contract changes will cost significantly more to obtain data.

4. Needs Assessment

The purpose of the needs assessment was to determine the high-level requirements associated

with data acquisitions and whether the existing problems associated with data acquisitions are

Agency wide or program specific. The needs assessment report is used to develop the future

contract language and to enhance its effectiveness. The needs assessment was performed through

surveys and focus group discussions. The key findings follow.

4.1 Digital Data Standardization

Digital data standardization, regardless of the file or data format used, is needed for all data

deliverables. As such, future procurement solicitations are to address and place emphasis on, but

not limit to, the following categories and include as deliverables along with addressing “how to”

accomplish them within the SOW and other sections of the RFP:

a. Ensure consistency of data and data use across systems.

b. Ensure minimal redundant data collection and entry.

c. Ensure maximum utilization of relevant technology.

d. Ensure audit trail accessibility.

e. Ensure rapid retrieval of audit trail information for change processing.

f. Ensure effective analysis of metrics.

g. Ensure improved data acquisition time lines.

h. Ensure improved data review and integration.

Administration Regulations (EAR). Reference EDR Log #: _6808_ NASA KSC Export Control Office, (321)

867-9209.

98 of 217

Digital data standardization is considered and required when the following program requirements

exist:

a. The potential for reuse of data in compliance with Office of the Federal Chief

Information Officer’s Memorandum for the Heads of Executive Departments and

Agencies M-13-13, Open Data Policy, in accordance with internal data clearance

processes for release to public.

b. A need exists for interoperability of standardized data among Centers, academia,

industry, platforms, and contractors/programs.

c. The need to provide relationships between data for performing program management,

systems engineering, and operational functions.

d. Contract closeout.

4.2 Data Definition and Interoperability Requirements

NASA must provide data definition and interoperability requirements written into program

contracts to leverage a data-centric approach for digital asset data management. The

requirements should be defined by NASA policies that generate content for inclusion in NASA

Request for Quotes (RFQs), Request for Information (RFI), and Request for Proposals (RFPs)

templates and preparation handbooks.

4.3 Data Acquisition

NASA must provide data acquisition requirements to enable the reference and reuse of data

through a Program's full life cycle. These data acquisition requirements should be present during

RFP/RFQ development to establish integrated data architecture for a Program's information

systems architecture (ISA), data architecture (DA), and Information Systems (IS) capability

roadmap. The ability to meet data exchange requirements should be a part of the contract

performance metrics that the contractor must report on and be evaluated on throughout contract

execution.

4.4 Data Rights

NASA must ensure access to technical data (recorded information used to define a design and to

produce, support, maintain, or operate a system). This is critical to life-cycle sustainment of a

system. Critical decisions made early in the acquisition process address data needs over the

entire life cycle of the system.

It is critical for the contractor to assess long-term data rights requirements and corresponding

acquisition strategies prior to initiating a response for proposal to acquire systems, subsystems,

or end items to ensure they provide for rights, access, or delivery of technical data that the

99 of 217

Government requires for systems' total life-cycle sustainment. Furthermore, the delivery of

technical data and associated rights at reviews and documentation of the strategy in the

Information Support Plan and associated data planning documents should also be addressed.

NASA must ensure science data is retrieved and accessible for open sharing. Science data

products include data sets generated by the project that include the science data itself, associated

ancillary data, and aircraft navigation data. The contractor must summarize all science data

products to be generated and documentation for correct and independent use of the data. The

expected range of use to be supported by this documentation should be indicated. Some types of

data sets that should be considered for inclusion are:

 Metadata,

 Low-level processed data,

 High-level processed data,

 Scientific results,

 Science algorithm source code,

 Algorithm theoretical basic documents (ATBDs),

 Data quality documentation.

4.5 Request for Proposal (RFP) Language

There are several areas of the RFP that need language to ensure program data acquisition

downstream. In addition, creating a template that includes both prescriptive language and

guidance for organizations to describe their data and how they want to access it, allows the

organization to customize their instructions to the potential Offerors. Specific sections of the

RFP include:

a. SOW – This is where the functional and technical requirements reside within the

contract package, typically within Section C of the government request package. The

requirements will include the types of data the government identifies for use

throughout the life of the contract, how they want to access data, and the process of

transferring the data at contract end. The Offeror provides this information in their

proposal; however, the information may not be explicit in the contract, but rather is

contained within the DRD (Data Requirements Description).

b. DRD – In this case the DRD is a template that requests details for the information that

was requested in the SOW. It must be submitted with their proposal. The Offeror

should provide the same approach to handling Data as they submitted in their

proposal. This remains in the contract within the DRD. Contracting Officers, not

always but often, will go to the SOW as the rules of the contract, often at the expense

100 of 217

of the DRD. They expect to see the rules in the SOW. For this reason, it needs to be

in both places.

c. Cost Volume – The cost of maintaining data in a centralized place, making it

accessible to the government, and then transferring the information at contract end

has a price tag that is always more than expected. To get the best price, the cost must

be set at contract start. To achieve this, the Offerors must submit their cost to the cost

volume as a separate line item. This sets the cost at contract start because the cost

volume is in the contract. This will be critical for fixed-price contracts.

4.6 Procurement Information Circular (PIC)

To have the data requirement pushed to all NASA procurements that have data requirements

(e.g. not hardware or software purchases), a PIC needs to be put in place so all the Contracting

Officers understand the data language requirement. The PIC directs them to include it (if it

requires data) into each Procurement. They will provide the requirement to the board chairs. The

Contracting Officer will not be responsible for understanding the requirements or implementing

them. That will be the responsibility of the chair/board member assigned to the action. A

document with guidelines and the prescriptive language of how and when to use the data

language will accompany the PIC.

4.7 Training

Each Center needs to appoint a point of contact from their Chief Information Officer’s (CIO’s)

office that can work with the boards to guide them through the process. Each POC needs training

on the process before working with the boards.

4.8 Proprietary Data and Intellectual Data Rights

NASA recognizes the right of suppliers to create and maintain a competitive advantage.

However, NASA seeks access to or acquisition of relevant data for efficiency and safety reasons.

Proprietary data and intellectual data rights must be addressed to the extent the contractor cannot

label data as proprietary to avoid data sharing. NASA seeks to explore ways to access the

necessary data while still respecting the interests of the suppliers. This language is legal in nature

and therefore needs to be provided by Legal and Procurement.

5. Contract Language

NASA shall ensure that contractor data delivered to a single authoritative source is acquired

through contract, and that Data Requirements Descriptions (DRDs) specify data to be delivered

in specified electronic data formats, in lieu of “contractor format acceptable” or similar

language. Contracts shall specify the required delivered data transaction scope, data delivery

formats, metadata, naming standards, and data exchange standards. The definition of data

formats and transaction sets shall be independent of the method of access or delivery.

Regardless of the format of acquired data, the contractor shall mark data provided with less than

unlimited rights with the appropriate legend as set forth in FAR 52.227-14, Alternates II and III.

See the following sections for specific language for all contracts.

5.1 Model-Based Enterprise (MBE) Plan

The Contractor shall provide an MBE Plan to be approved by the Government for all contracts

requiring data

deliverables. The MBE Plan will be used to document the data management

infrastructure that will be put in place throughout the contract and provide periodic reporting of

the data produced by the contract. Refer to Appendix J.

5.2 Data Rights

NASA shall obtain and maintain appropriate data rights for all data produced by the Contractor

to be provided to NASA during and at Contract end. NASA shall address intellectual property

rights on an individual basis in conjunction with Procurement and Legal Offices.

Contract language should include following:

“The [Agency] owns the rights to all data and records produced as part of this contract. All

deliverables under the contract are the property of the U.S. Government for which [Agency] shall

have unlimited rights to use, dispose of, or disclose such data contained therein as it determines

to be in the public interest. Any Contractor rights in the data or deliverables must be identified as

required by 48 CFR § 52.227-11, Patent Rights-Ownership by the Contractor; 48 CFR § 52-227-

12, Reserved; 48 CFR § 52-227-13, Patent Rights-Ownership by the Government; 48 CFR §

52.227-14, Alternates II and III, Rights in Data—General; 48 CFR § 52-227-15, Representation

This section contains each of the categories and requirements associated with Data Management in contracts. The

intent is to choose each category and specific requirement(s) that applies to the contract’s use of data. Contracts

that have science or engineering as a core competency tend to use the data differently and have different

requirements that need to be reflected in the SOW. The individual requirements found in these sections should be

viewed as options to be selected as they apply to the contract and use them as appropriate to develop your SOW.

The term “data” will be used throughout this section to cover the terms data, information, and knowledge.

Issuer’s legal organization should be part of standard review process, including all specific binding language.

of Limited Rights Data and Restricted Computer Software; 48 CFR § 52.227-16, Additional

Data Requirements; 48 CFR § 52-227-17, Rights in Data-Special Works; 48 CFR § 52-227-18,

Rights in Data-Existing Works; 48 CFR § 52-227-19, Commercial Computer Software License;

and 48 CFR § 52.227-20, Rights in Data-SBIR Program.”

Flow down of requirements to subcontractors:

1. “The Contractor shall incorporate the substance of this clause, its terms and

requirements including this paragraph, in all subcontracts under this [contract

vehicle], and require written subcontractor acknowledgment of same.

2. Violation by a subcontractor of any provision set forth in this clause will be attributed

to the Contractor.”

Regarding Federal Acquisition Regulations (FARs):

Government personnel preparing agreements (e.g. RFIs, SOWs, PWS, etc.) need to understand

the distinction between:

1. FAR parts and subparts that are guidance and direction to the Government and FAR

Clauses, and

2. FAR Parts and Subparts incorporated by Reference, that are Contractually binding

upon the Contractor and the Government.

Regarding the term “Data Rights,” which is often used to refer to the Government’s licensing

rights in two major categories of valuable intellectual property:

1. Technical Data (TD) includes any recorded information of a scientific or technical

nature (e.g. product design or maintenance data, and computer software

documentation (CSD)).

2. Computer software (CS) includes executable code, source code, code listings, design

details, processes, flow charts, and related material.

An Intellectual Property Strategy needs to be developed early to help program/project

management to ensure that all TD, CS, and associated license rights required for procurement

and sustainment of a system are available throughout the system’s life cycle.

1. Sustainment activities include re-bid/procurement, maintenance, repair, modifications

or interfacing/interoperability activities, and upgrades or technology insertion.

2. A priced option may be used to address uncertainty regarding data deliverables or

data rights that may be needed in the future but that are not ordered up front.

3. The deferred delivery clause (DFARS 252.227-7026, Deferred Delivery of Technical

Data or Computer Software) and necessary CDRLs are used to delay delivery, when

the specific data requirements are known, until the Government determines when the

data deliverables should be provided.

4. The deferred ordering clause (DFARS 252.227-7027, Deferred Ordering of Technical

Data or Computer Software) is used to delay the ordering of data generated in the

performance of a contract until the Government determines what and when additional

data is needed.

Data deliverables and data rights issues may be identified and resolved by:

1. Requiring Offerors to assert all restrictions on deliverable TD and CS–both

commercial and noncommercial–up front, in their proposals,

2. Evaluating the data deliverables and data rights being offered, and

3. Negotiating for mutually agreeable special license rights where standard license

categories do not meet both parties’ needs.

The Government’s license rights to a contractor’s TD and CS generally depend upon the extent

to which the Government funded the development of the technology, whether the technology is

commercial or noncommercial, and any negotiations for mutually agreeable “special” license

agreements. Some types of data qualify for Unlimited Rights regardless of development funding

source such as “form, fit, and function (FFF) data” and data necessary for operation,

maintenance, installation, and training (OMIT) purposes (excluding detailed manufacturing and

process data).

The FAR clauses do not by default require delivery of TD or CS–the Government must include

specific delivery requirements in each contract (refer to Table 3, Specific Contract Delivery

Requirements). Mere access may not protect the Government’s interests. Consider a priced

option when needs for data delivery or data rights are uncertain.

6. Conclusion

A NASA-wide policy or standardized approach for ensuring data integrity, access, and

successful transfer does not currently exist as practices. It varies across the Agency. The team

did find instances where policies are currently in place or in work and fully acknowledges the

flexibility of each individual program, project, or contract to tailor. In the absence of a NASA-

wide policy, contracts should ensure contract language exists to identify and review data

acquisition requirements and, in particular, the rights the Government should have in using the

delivered data for the full program. This must be done as early as possible in project planning to

establish an integrated set of data requirements. The requirement to deliver and manage data in a

digital environment influences the manner in which data delivery requirements are levied on

existing and future contracts. Ongoing contracts should consider contract modifications to

require the delivery and management of contractually delivered data in a digital environment on

contracts that do not currently require data delivery in a digital format.

NASA should acquire only the essential Contractor-originated data required to meet all program

life-cycle requirements. Every attempt should be made to integrate all functional specialties, e.g.

safety, reliability, quality, logistics, test, verification, etc., to minimize data acquisition

redundancies and inconsistencies. This integrated effort must include sub-projects within the

various programs.

For ongoing NASA Earth science contracts, continue to use the following guidance:

a. NASA will plan and follow data acquisition policies that ensure the collection of

long-term data sets needed to satisfy the research requirements of NASA's Earth science

program.

b. NASA commits to the full and open sharing of Earth science data obtained from

NASA Earth-observing satellites, sub-orbital platforms, and field campaigns with all users as

soon as such data become available.

c. There will be no period of exclusive access to NASA Earth science data. Following a

post-launch checkout period, all data will be made available to the user community. Any

variation in access will result solely from user capability, equipment, and connectivity.

d. NASA will make available all NASA-generated standard products along with the

source code for algorithm software, coefficients, and ancillary data used to generate these

products.

e. All NASA Earth science missions, projects, grants, and cooperative agreements shall

include data management plans to facilitate the implementation of these data principles.

APPENDIX C

MODEL-BASED DATA DEFINITION

C.1 PURPOSE

NASA engineering and partners use models defined through model-based data definition as part

of model-based enterprise (MBE). This NASA Technical Handbook provides a means for

consistent model-based data definition, direction, and execution supporting model-based

acquisition methods, practices, and protocols as defined and utilized per program and Center

definition.

MBE is an integral part of the technical baseline that includes the requirements, analysis, design,

implementation, and verification of a capability, system, and/or product throughout the life cycle.

Model-based engineering and definition have multiple meanings to many people, and the intent

of this Appendix is to identify and define the elements of MBE that are impacted and driven by

the program DRD.

To provide a common baseline of definition and guidelines, the following sections discuss not

only the premise of the description but also a definition as provided by the National Institute of

Standards and Technology, NASA, and commercial companies doing business with NASA.

C.2 MODEL-BASED DATA DEFINITION

Model-based data definition is a subset and critical element of MBE and is intended to increase

the probability of mission success by increasing the availability, effectiveness, integrity, fidelity,

and efficiency of model data and data interchange/integration across like as well as disparate

systems. The end goal of data definition is to provide and improve the availability of the right

data to the right people at the right time, thereby reducing risk.

The process for the management of technical data (models) is required by NPR 7123.1 for

ensuring that the digital data required are captured, stored, version controlled and managed, data

integrity is maintained, and data dissemination processes and data definition and integrity meet

contracted requirements.

Within the MBE framework, model-based data definition defines not only the context of the data

definition but also the management of product data as it is defined for use (Process). It enables

informed decision making across the product development cycle and applies a consistent set of

business solutions that support MBE elements such as MBSE, model-based manufacturing

(MBM), model-based inspection (MBI) (utilizing CAD for CMM inspections).

Model-based data definition:

a. Enables process optimization and maturity using MBE as a baseline and establishes a

paradigm to help NASA programs achieve the highest level of collaboration, interoperability,

efficiency, and data availability. The implementation of a fully digital MBE environment is

necessary to comply with the program requirements.

b. Defines and enables technological requirements, whereas IT systems across NASA

need to be made interoperable or integrated to the extent needed to provide a secure, readily

accessible environment to enable required collaborative MBE capabilities.

c. Is the underlying architecture required to tie data and processes together and provides

the framework for collaboration and interoperability. MBSE is the systems engineering subset of

MBE.

d. Provides the foundation and capability to orchestrate procedural events such as design

reviews from authoritative data sources.

Architecture, infrastructure, and data definition are at the core of this framework on which all

collaboration (Center to Center and Center to prime/partner), workflows, data management, and

data sharing will be built.

Additionally, MBE elements to be considered and included in the data definition or the DRD are

NOT restricted to only CAD models and may also include many of the MB(x) definitions listed

in Appendix D.

It is imperative that all parties as defined in the DRD take notice to the consistency of definition

and follow NASA policies and standards to ensure compliance.

Notable elements for focus during data definition are discussed in sections C.3 through C.15 in

this Appendix. See Appendix G for use cases for establishing MBE elements and

interoperability requirements.

C.3 “SYSTEM MODELS” VIA MODEL-BASED SYSTEMS

ENGINEERING (MBSE)

MBSE is a method to drive system models that represent functions, requirements, and conceptual

systems and is present and interactive within the life cycle (concept definition through

retirement). The intent of MBSE is to facilitate traditional systems engineering resulting in

enhanced communications, specification and design, system design integration, and reuse of

system artifacts and models. MBSE can support both engineering data and business data.

In MBSE definition and engineering, a system model is at the center of the developmental

process, from requirements development, through design, implementation, and testing. The

model is a specification that is continually refined throughout the development process. After

model development, simulation shows whether the model works correctly.

It is expected that in the MBE environment, MBSE will extend to domains to support complex

predictive and effects-based modeling that include integration of engineering models with

scientific and phenomenology models; social, economic, and political models; and human

behavioral models

While the output of MBSE is an analytical system model, it is sometimes developed in

SysML™. In an MBE environment, MBSE is a key critical success factor in that it helps teams

focus thinking to develop engineering work products. MBSE captures the decisions, performs

analyses, and produces review and audit materials.

An MBSE system model can incorporate other abstract models to document design sets and

graphical presentations of process flows that enable group participation in concurrent

engineering. This includes CAD models, digital manufacturing models, as-built models, model-

based testing, and logistics functions. MBSE provides the capability for these reviews to be

conducted with a single-source interconnection model that provides viewing of the system

models and their interactions from different perspectives (i.e. discipline-dependent views).

All uses of the MBSE artifacts must be clearly defined per program and defined in the program

DRD.

C.4 Requirements

The size (scope and scale) of a program/project has an impact on the MBE environment and

solution but is not deterministic in regard to requirements for managing product data. Factors

such as the nature of the mission; mission class; the amount and types of data; data acquisition;

sensitivity; retention needs; the location, timing, and duration of data access; and the

organizational relationships of participants are important for characterizing the demands that

programs/projects make on expected MBE capabilities.

Requirements management in a model-based program/project environment provides a

framework for defining, refining, documenting, and maintaining the requirements of the

product(s) produced by the program/project. The requirements are to be maintained and managed

throughout the entire life cycle of the project.

Program/project requirements are defined and documented by the program/project’s systems

engineering and integration functions, or their designees, and documented in the Systems

Engineering Management Plan in accordance with NPR 7123.1.

Requirements should be defined in the DRD and:

 Allocate requirements to various program/project organizations for decomposition.

 Define the relationship of requirements to other information in the MBE environment.

 Provide the framework for requirement derivation and a scheme for parent and child

requirement relationships.

 Provide links for access to authoritative requirement information.

 Allow the definition and management of detailed information attached to the

requirement such as margins, technology readiness levels, risks, and cost data.

 Be traceable to its source, downstream to its implementing product component, and to

their verification and validation activity.

 Be securely controlled and traceable from beginning to end of life (history and use).

 Be captured in a virtual database that provides secure but easy access. Requirements

management tools should provide automatic notification of requirement changes and

impact to flow-down or linked requirements.

C.5 COMPUTER-AIDED DESIGN (CAD) DATA (MECHANICAL CAD

[MCAD]/ELECTRICAL CAD [ECAD]/COMPUTER-AIDED

ENGINEERING [CAE]/COMPUTER-AIDED MANUFACTURING

[CAM])

Effective CAD data management enables immediate access to needed PDD but must define

relationships between all associated CAD parts and assemblies. CAD management of MCAD,

ECAD, and CAM parts and assemblies have to include management of systems and software

across the entire program/project life cycle.

Items to be considered and resolved within the definition of the DRD should address and take

into consideration problems seen and occurring with managing CAD data because:

a. Incomplete information causes iterations—not all CAD objects come with CAD data

packages.

b. CAD naming conflicts—may have multiple names for the same parts.

c. Change management—lack of governance needed and defined with approval, as

names may change—no way to see if it is the same geometry.

d. Data conversion—CAD drawings are converted to a defined standard for consistency

(see Appendix F).

e. Broken CAD links when moved manually—links and relationships are broken losing

traceability.

f. Inconsistent CAD and model version/revision controlled.

g. Inconsistent modeling standards.

h. No design intent captured or shared.

Programs/projects should work to define, agree with, and implement a CAD data management

environment in which:

127 of 217

a. MCAD (parts and assembly) models and associated data are captured in a virtual and

accessible database.

b. Relationships between all associated MCAD parts and assemblies are defined.

c. Ability to rename to-be-determined (TBD) items prior to release into MBE exists, or

if late, fall under a change control board for traceability.

d. Structured check-in/checkout process and revision control ensure data integrity.

e. Workflow and automatic notification capabilities enable adoption of product

development best practices.

f. ECAD and systems (parts, files, and assembly) data are available through a virtual

database.

C.6 Part Manufacturing Information (PMI)

The mechanical properties and design for manufacturing instructions of a product (for example,

digital mock-up (DMU), digital computer-aided test model) and PMI have to be properly

examined and checked for content, context, and maturity. This can involve checking the overall

geometry with regard to dimensions and shape, interference checks, and collision checks for

assembly and disassembly, as well as design space checks.

For these purposes, the geometry, product structure, and metadata are displayed and analyzed in

a DMU application; however, results are captured in the model data definition. A distinction is

made between static and dynamic DMU analysis. In the case of static DMU, an examination of

the static parts is performed. In the case of dynamic DMU, the dynamic parts or assemblies are

examined.

While visualization is critical to convey design intent and analyze form and fit, information used

to drive manufacturing (PMI) and assembly is also critical. DMU is an excellent source of

information and graphics to enable and provide quality instruction downstream. Tracking and

capture of this information is equally important and has to be defined as a critical path item in the

DRD.

As a rule, a simplified, tessellated representation of the envelope geometry is usually sufficient

for use in DMU. In the case of measurements, however, it should be noted that the level of

tessellation accuracy always must be higher than the required measuring accuracy.

The most important items to consider are:

128 of 217

 The availability of applications that support the respective required DMU

functionality (e.g. assembly checks and collision control).

 Use of models from different source systems (multi-CAD).

 High-quality examination of large assemblies.

 Transferability of kinematics from the original model to the target model for dynamic

DMU analysis.

 Development of a TDP from which other Centers, partners/primes, and suppliers can

derive design intent to properly manufacture the product.

C.7 Modeling and Simulation (M&S)

Results from M&S are rich data used daily for making critical decisions in design, development,

manufacturing, ground operations, and flight operations. The program/project manager and

delegated Technical Authority(s) have the responsibility for ensuring the credibility of the results

from these M&S activities (reference NASA-STD-7009, Standard for Models and Simulations

and NASA-HDBK-7009, NASA Handbook for Models and Simulations: An Implementation

Guide for NASA-STD-7009). Models and resulting simulations fall under the governance of the

DRD to ensure all parties are working with the latest, common data.

Confidence in M&S results is achieved by:

a. Identification of best practices to ensure that knowledge of operations is captured in

the user interfaces (e.g. users are not able to enter parameters that are out of bounds).

b. Development of processes for tool verification and validation, certification, re-

verification, revalidation, and recertification based on operational data and trending.

c. Development/identification of standards for documentation, CDM, and quality

assurance.

d. Identification of any training or certification requirements to ensure proper

operational capabilities.

e. Development/identification of a plan for tool management, maintenance, and

obsolescence consistent with modeling/simulation environments and the aging or changing of the

modeled platform or system.

f. Development of a process for user feedback when results appear unrealistic or defy

explanation.

129 of 217

g. Development of a standard method to assess the credibility of M&S presented to the

decision maker when making critical decisions (i.e. decisions that affect human safety or mission

success) using results from M&S.

h. Assurance that the credibility of M&S meets the project requirements, and the

appropriate documentation is captured and preserved.

i. Reinforced verification and validation (V&V) models and practice.

C.8 Document Management

Documents such as specifications, policies, and test results (other than CAD and systems

models) provide an important communication medium using prose. This facilitates a broad

communication of program information to a broad set of engineering and business backgrounds.

MBE is evolving to be the source of the document production, where documents are

communication methods and the models are the authoritative source.

C.9 Documentation and Archiving

For the purpose of documenting and archiving engineering data, it is normally necessary to

factor in exact data representation, including all metadata and PMI. The DRD must be prolific

throughout the life cycles but also needs to define consistency and accessibility even after design

is complete.

The latter is especially important with regard to product approval and product documentation if

drawings and technical documents are being replaced by digital 3D models. Compliance

requirements often need to be satisfied.

The most important requirement relating to the documentation and archiving of engineering data

is that all relevant information be stored in a format that can be read irrespective of a specific IT

infrastructure and after a long period of time; in the aerospace industry, for example, the Long

Term Archiving and Retrieval (LOTAR) activity (http://www.lotar-international.org/lotar-

standard.html) addresses archiving of data for long life-cycle programs.

The most important items to consider are:

a. Ensuring proper consideration is given to all product data.

b. Ensuring problem-free combination of data from different source systems.

c. Ensuring that the data can be accessed even after long periods of time (standardized

format).

C.10 Portable Product Life-Cycle Management (PLM) Document

In modern product development processes, the utilization of 3D information does not end in the

engineering department. Integrated product development (sometimes referred to as concurrent

engineering) requires that departments/functions such as purchasing, quality assurance, technical

documentation, configuration management, planning, manufacturing, operations, maintenance,

and sustaining also have to be able to access 3D information in combination with a wide variety

of different documents such as bids and requests for quotes, quality control checklists, technical

and manufacturing documentation, etc.

It is important that the program DRD owns this responsibility and ensures that this content can

be combined in a multimedia container that includes all the information and can also be used

offline.

The most important items to consider are:

a. Information in the form of 3D data, metadata such as 2D representation, text data, and

binary data can be combined in a single file and can be managed there.

b. The data can be combined easily with information from various source systems.

c. Comprehensive control options for file access (intellectual property protection) exist.

d. Easy-to-use, cross-system viewers are available.

C.11 Configuration and Data Management (CDM)

CM in the model-based environment provides the structured environment with a framework for

programs/projects to develop and control their requirements and associated engineering products

and information, providing a system to reconcile and enforce accountability between various

bills of material (BOMs) covering several configurations and restructuring use cases such as

BOM splits, merge, substitutes, change action propagation, etc.

The CDM structured environment must address and define the following:

a. Functional and performance characteristics of the program/project’s products.

b. Functional, allocated, and product baselines.

c. Requirements for the design, manufacturing, testing, checkout, training, maintenance,

operations, sustaining, and disposal of the products.

d. Verification that the end product is in compliance with the requirements and

associated information.

e. Traceability of waiver, deviation, and non-compliance of requirements information.

f. Retention, security, and data integrity of records.

g. The determined level of CM by supporting organizations.

The program/project-level CDM processes need to flow down to establish and maintain

consistency of multi-level supplier organizations’ products with requirements through the entire

program/project life cycle via the MBE environment.

CM creates a consistent and systematic method for products delivered to the programs/projects

that:

a. Identify the product configuration (architecture, current status, and related

information) at KDPs and other times.

b. Systematically control changes to the product configuration.

c. Maintain the integrity and traceability of the product configuration throughout the

product life cycle (for example, operations anomaly functions may require fast access to

information from the earliest product phases).

d. Preserve and retire product records throughout the product life cycle to be defined in

NPR 1441.1, NASA Records Management Program Requirements.

The CM administrative function defined in SAE EIA-649-2 shows how the product data is to be

released. Once data has been released, it follows the structured procedures and processes

established by the program/project’s CDM and MBE Plans.

The program/project manager and delegated Technical Authority(s) define and document as part

of the MBE Plan what product data are released, when that product data are to be released,

events that necessitate product data change, and the processes that provide the visibility of the

product data configuration life cycle for internally and externally produced product data.

C.12 Bills of Material (BOM) Product Breakdown Structure

A product breakdown structure is a hierarchical program/project view of the relationships of the

hardware and software products and component products. Product structure provides a platform

on which an entire program/project product family can be based. Product structure involves

decomposition of the overall functionality of a product into a set of defined functions, the

component parts of the product that provide those functions, and the specification of the interface

between the components—how components interact together in the product as a system. It is a

product data structure that captures the end products, its assemblies, their quantities, and

relationships.

A BOM is a functionally dependent view of a subset of the product structure that includes the

physical items and is a formally structured list for an object (semi-finished or finished product)

that lists all the component parts of the object with the name, reference number, quantity, and

unit of measure of each component. MBE should provide for traceable documentation of all

changes to the BOM, including when and why it was changed, which documentation

implemented the change, who approved the changes, and the disposition of the affected items.

Problems occur with the development and use of BOMs because:

a. Only the “as-designed” BOM is managed in engineering.

b. The proposal BOM is created, then not carried forward.

c. Not all data delivered are related to part definition.

d. No product structure is delivered.

e. Effectivity for BOM change is limited to a single change and by date only; most

recent is all that is saved.

f. Substitutes and alternatives are managed as separate BOMs and products.

Programs/projects should work to define and implement a product structure and BOM

development that can:

a. Manage product structure and BOM data.

b. Capture and manage substitutes and alternative parts.

c. Provide revision control and history of product (BOM) data.

d. Manage multiple views of the BOM, including as proposed, as designed, as built, and

as launched.

e. Manage effectivity by event, date, lot, or serial number as necessary.

The product structure should be documented in the MBE Plan and provides a simple, concise

view of the product that can be used as the central point of reference for all information

describing and related to each element, subsystem, assembly, subassembly, and part comprised

within the structure. The complete product breakdown structure segment list should be defined,

including design data for an assembly and/or subassembly such as as-designed (Engineering or

EBOM), as-built or as-manufactured (Manufacturing or MBOM), as manifested, as flown, and as

disposed, beginning either at the highest level (system) or lowest level (component) to access all

related data based on access privileges.

A good product structure should:

a. Be a decomposition/interrogation of the system into its parts.

b. Define the complete segment list, including design data for an assembly and/or

subassembly such as:

(1) As designed—a product structure representing the configuration after release,

before manufacturing is started.

(2) As built (as manufactured)—a product structure that represents the configuration

as it has been manufactured and delivered to the NASA inventory.

(3) As manifested—a product structure representing a configuration designated for a

specific flight.

(4) As flown—a product structure representing a configuration that has flown.

(5) As disposed—a product structure representing a configuration that has been

decommissioned.

Provide the capability for an individual to start at the highest level (system) to access all related

data (based on the individual’s access privileges) by drilling down to the lowest component of

the system, as well as walking up from the lowest component to the highest level, including, but

not limited to, access to supporting design documents such as analysis reports, test reports,

requirements, and V&V checklists.

Components include hardware, software, and configurable logic devices as shown in the

examples below:

a. System.

b. Segment.

c. Element.

d. Subsystem.

e. Assembly.

C.13 Engineering Release and Change Management

All engineering releases, changes, and supporting information are properly managed and the

terminology of the engineering release process properly defined. The change process is to be a

multi-level supplier, closed-loop process with changes automatically integrated, routed, and

closed looped with the impacts of the change easily visible. A history of changes is to be

maintained.

Program/project managers, delegated Technical Authorities, and appropriate engineering

organizations consider engineering release of data that occurs during the following life-cycle

states/phases as part of the development of MBE engineering release and change management:

a. Requirements definition.

b. Design and development.

c. Fabrication/manufacturing.

d. Test and verification.

e. Flight and operational data.

The term release (as a verb) is to authorize for dissemination a particular version of a product

and/or product information that is made available for a specific purpose. The activities associated

with the term “release” can change during these different life-cycle states/phases. For example,

release of the design configuration makes available the set of design information, incrementally

released to date, by the development activity for a product during a product’s definition

(development) phase.

The term “release” can be used in a given context to mean “you can do X with Y,” where both X

and Y vary. For example:

a. Released Upper Stage CAD model of Liquid Oxygen (LOX) tank (Yproduction)

means the prime can start manufacturing (Xmake or buy).

b. Released trade study of material choices for Upper Stage LOX tank (Y’) means

designers can proceed with Upper Stage tank design work (X’).

A data object is defined by the object itself, its metadata (including effectivity), and its state (e.g.

“in work,” “under review,” “released”). Additional data are required to indicate how the data

objects relate to other data (e.g. effectivity). A method for capturing the object and relational data

is to be developed for usage, change control, and integration of its intended use (effectivity and

authorized usage).

867-9209.

135 of 217

The object’s type alone does not necessarily determine its usage without supporting metadata.

For example, a CAD model can be released as:

a. Design definition model for manufacturing (e.g. Upper Stage LOX Tank Production

Model release), or

b. Intended for use in outer mold line development.

Process details depend on both object type and intended use and are not exclusively defined by

project phase, e.g. more design work is done in the detail design phase; but design work is also

done in operations to support block changes and sustaining engineering. Object type and usage

are considered along with project and product phases during process development.

The program/project has to have confidence that data in a given state means the same thing to

everyone:

a. A process that produces a known object in a known state is to be provided. For

example: Product definition package (3D CAD models, 2D drawings, and material

specifications) “released for manufacturing” always means released for production activities

such as manufacturing planning, computer-controlled manufacturing machine programming,

procurement, inventory management, etc.

b. If work is distributed among Centers or multi-tiered suppliers, the program/project

needs to assess what release means across context and ensure effective integration.

Different objects have different uses and users, and it is those use cases that should determine the

meaning of the states (e.g. preliminary release-development use only):

a. MBE and CDM distinguish between types of objects and their intended/authorized

usages. For example: Several external suppliers use two design paths: prototype and

manufacturing; 3D CAD models that are released for prototyping are NOT released for

manufacturing.

b. Within each use case and for each product data category (i.e. CAD, parts assembly,

analysis, etc.), the program/project manager and delegated Technical Authority(s) define the life-

cycle states (in work, approved, released, etc.).

The program/project manager, delegated Technical Authority(s), and engineering determine if

some data needs special handling and what standards should be used or developed to address this

data. Examples of these data objects/types are engineering models/design/analyses (e.g.

SysML™, 3D CAD/CAE, etc.). Another data type, for example, could be MATLAB designs

used for modeling of guidance, navigation, and control (GN&C) algorithms and then has source

code auto-generated for integration into flight software.

System synchronization, the process of collecting a known set of configurations for a system-

wide test at various points in the overall system life cycle, enables early integration testing, as

well as early investigation of alternatives.

With large amounts of externally provided data, it is difficult for NASA programs/projects or the

lead systems integrator, due to cost and other factors, to insist that suppliers (e.g. primes,

partners) all follow a defined/specific process. For this case, the program/project can and should

insist that processes have key states that map to defined program/project core states:

a. The MBE Plan should provide a mapping of source states to destination states that

provides confidence that the data can and will be used for the intended purposes and not

unintentionally misused. The MBE Plan should lay out clear contractual requirements using the

contract’s SOW/PWS and include DRDs utilizing standards such as MIL-STD-31000. (See

Appendix A.) For example, an external supplier can call it “manufacturing release,” one NASA

Center can call it “final release,” and another NASA Center can call it “engineering release,”

which will be inconsequential when delivered per DRD.

b. Source-to-destination mapping confirms that all these are the same as the

program/project-defined “production release.” Refer to Figure 2, Notional State Compatibility

Map.

C.14 Parts and Library Management

Parts data handling is distributed across Centers and out to primes, assigned to multiple different

functional areas within projects, and maintained within locally controlled design environments.

Effective handling of how parts are identified, defined, categorized, authorized, and specifically,

how CAD data objects are handled in systems for design and sustaining engineering, are critical

to performing the job of systems integrator and must be defined in the DRD.

When part numbers exist without exact specifications, or exist with a part number that is similar

to the part number of another component, time and resources will be required at a critical point in

product development to reconcile the discrepancy.

Part number proliferation causes confusion and duplication—not only duplication in effort but

duplication in cost for maintaining parts inventory. Parts data handling processes should be

defined upfront and should be enforced and followed for such matters as part naming and

substitutes/alternatives.

Establishing parts libraries is critical in program/project development. Multiple libraries can exist

such as part definition libraries, M&S libraries, and CAD libraries. Maintenance of these

libraries can be spread across multiple organizations, internal or external to the program/project,

and usage can be shared by many users across organizational boundaries. It is imperative that the

programs/projects understand and document the library structure and ensure approved practices

are established.

A CAD parts library functioning in an MBE environment provides an efficient and flexible

framework for developing, promoting, using, and maintaining CAD common parts libraries,

registries, catalogs, and associated support mechanisms. The description of these libraries,

registries, catalogs, and databases may include terminology such as "standard," "preferred," and

“electronic, electrical, and electromechanical (EEE).” The CAD functions supported by the

libraries may include ECAD, MCAD, and CAM.

A CAD parts library’s functions should include the following:

a. Accommodate the use of multiple CAD common parts libraries by the organizations

within the enterprise while requiring appropriate identification, naming, and usage; establish

processes to minimize the number of duplicate labels for the same physical part.

b. Provide a mechanism for a CAD developer or integrator to determine if a part is

already defined in a common library within the enterprise's MBE environment.

139 of 217

c. Establish rules and business processes to accept individual new part definitions and

designations into the program/project’s common parts catalog, registries, and naming

conventions.

d. Establish rules and business processes to accept wholesale existing part definitions

and designations (entire existing parts libraries) into the program/project’s common parts

catalog, registries, and naming conventions.

e. Establish security rules and business processes for access to CAD parts that are

proprietary, intellectual property, or designated as SBU.

f. Establish and support audit and compliance functions to verify that naming

conventions, configuration and data management, and data architecture requirements have been

satisfied.

g. Establish rules and business procedures for external organizations that are not part of

the program/project’s MBE system to verify the uniqueness of proposed part names and enter

new parts into the program/project’s parts catalog system (delivery from an external source).

The scope of the CAD common parts library interoperability processes should be flexible. The

business processes for the CAD common parts library interoperability should be defined in the

program/project's CAD standards, CDM, and MBE documentation.

The DRD should describe how CAD standards will be applied over the program/project’s life

cycle, along with use of other internal or external standards, practices, settings, and supporting

tools with responsible parties. The DRD should also identify the program/project data or

documents that the CAD producer is to provide in addition to the CAD object to ensure full PDD

such as parts lists, materials specifications, and acceptance testing specifications and where this

material will be maintained.

C.15 Technology

MBE solutions should consider use of open architectures capable of supporting standards-

defined interoperability to address new and changing requirements.

Critical items to be considered include:

a. Architecture: Common definition for data hierarchy and collaboration. Top down and

bottom up links and relationships need to be considered and common across all program

participants.

b. Designing and implementing technical solutions for MBE require resources and

knowledge.

c. Even the simplest consolidation of users onto an existing system requires technical

support for the creation of accounts and the transfer of data, user training, and coordination with

customers, their managers, and the technical support team.

d. Consolidations that involve greater technical effort would require the creation of new

objects and the redefinition in the new location (or partition of an existing implementation), in

addition to the simplest consolidation.

MBE technology is often (but not solely) procured as a single integrated tool suite provided by a

single vendor comprised of commercial database management systems; custom-written software;

COTS interface tools; report writers; integration and utilities elements; and configuration,

auditing, administration, and definition files.

While the value and economies of such a solution are evident, no one tool can accommodate all

the needs in the heterogeneous environment present in many NASA programs/projects; and the

evaluation and selection of the correct technology for MBE is critical. Therefore, a key critical

success factor is the openness of the technology suite and standards-defined interoperability.

APPENDIX D

DIGITAL DATA COLLABORATION

D.1 PURPOSE

This Appendix provides guidance for digital data collaboration. Data through all life-cycle

phases can cross many entities that will likely change over time. That data today is generally

electronic, the design environment continues to move toward a models-based approach, and the

engineering/acquisition processes are more automated and demand a highly collaborative/social

workforce during all phases of the life cycle.

D.2 DATA INTEGRITY AND SECURITY

Data integrity during data acquisition continues to become more important to ensure the

following MBE artifacts, which can also be characterized as model-based x (MBx), are

considered, where “x” can and should include:

a. MBSE (model-based systems engineering)—design capture of logical, functional, and

behavioral system models leading to physical elements such as schematics, analyses, and CAD.

b. MBD (model-based definitions) - annotated 3D CAD models of design which capture

the physical system models leading to design definition and manufacturing elements such as

geometric dimensioning and tolerancing (GD&T), PMI, etc.

c. MBE (model-based enterprise) – an organization that uses model-based engineering

d. MBe (model-based engineering) - an approach to product development, design,

manufacturing, and life-cycle support that uses digital models to drive all engineering activities.

e. MBD (model-based definition)—design capture of schematics, analyses, CAD,

ECAD, CAM, 3D scan, surveys, field measurements, simulations, etc.

f. MBM (model-based manufacturing and assembly)—as designed/as built.

g. MBI (model-based inspection, including quality/compliance/assurance)—assurance

that the digital mode realized products meet defined maturity and content levels as consumed and

acted upon utilizing their product manufacturing information (PMI).

An established data definition framework captured and reported in the DRD ensures the

following:

 Security: All PDD is captured through a secure environment that meets the data’s

security requirements as defined by NPR 2810.1 regardless of the data’s form (digital

or hardcopy).

 Product Data Integrity: A single source of product definition where relationships

between all associated product documents are defined and managed.

 Automation: Workflow and automatic notification capabilities are provided.

Note: This planned environment ensures that all product data (CAD and product documents)

are captured and distributed per standard operating practice and are compliant with DRD

definition.

 Relationships between models and all the associated CAD parts and product

documents are defined and managed.

 Data, particularly CAD part numbers, are searchable by attributes and metadata.

 Product data are controlled as defined by contracts and data sensitivity and are

securely shared as needed and when needed.

D.3 DRD Digital Data Standardization

The need was recognized for NASA to adopt industry standards and approaches for digital data

interoperability to enable data interoperability and move beyond the storage of raw, uncorrelated

data. The following sections contain the contract language and the associated standards

necessary to execute digital data interoperability, which benefits NASA, its contractors, and

partners. DRDs are provided in Appendix A as a starting point for Centers to define their specific

needs.

Digital data deliveries have primarily been represented by digital scans of documents or in non-

machine-readable PDF (scanned/raster format) and stored in a file system or content

management system. This approach to data interoperability has fallen short in that data delivered

as part of a page-formatted document lack the relevant context required to effectively leverage

the data access and interoperability potential inherent to digital assets.

That is not to imply that exchanging digitalized data will solve the data interoperability problem.

Even digital data replication from system to system presents problems without a computer-

readable format that maintains the referential integrity of the data. As an example, experience has

indicated that the manual replication of data from one application to another could typically

create a discrepancy in 40 percent of the transferred data (refer to NIMA-RPT-004, Future Data

Exchange for NASA Programs). The disposition of that amount of data, per transfer, increases

the argument for standardization to bring about affordability and sustainability.

Proper data interoperability capability is achieved through the identification of IT standards and

the application of contractual methods to ensure implementation and alleviate the data

interoperability limitations that currently challenge NASA’s programs/projects. Multiple options

for data interoperability among NASA Centers and programs/projects with contractors, industry,

partners, academia, services, and platforms exist. This section provides information to ensure

that solution maturity is aligned with organizational requirements, proper data formats are

applied, and data transmission types are understood. In addition, guidance on contract language

is included to enable successful preparation of an RFP on data interoperability in Appendix B.

Digital data standardization provides:

a. Consistency of data and data use across systems.

b. Minimal redundant data collection and entry.

c. Maximum utilization of relevant technology.

d. Improved audit trail accessibility.

e. Rapid retrieval of the audit trail, enabling:

(1) Better informed, real-time management decisions concerning changes.

(2) Increased quality in CDM and control.

(3) Support for effectiveness of analyses of metrics.

(4) Improved data acquisition times.

(5) Improved data review and integration for:

A. Elimination or reduction of outdated or discrepant data copied into non-

authoritative sources.

B. Elimination of manual management of relationships between data.

MIL-STD-31000B, Technical Data Packages, defines the following:

a. Three-dimensional intelligent (3Di) technical data—a 3D viewable representation of

an item provided in a widely available software format (e.g. ISO 32000-1, Document

management — Portable document format — Part 1: PDF 1.7). This representation details the

complete technical description of the required design configuration to include, but is not limited

to, geometry, topology, relationships, tolerances, attributes, metadata, and other features

necessary to define a component or assembly.

b. 3Di format—the standard arrangement and organization of information within a 3Di

viewable representation of an item. This includes such features as the size and arrangement of

information blocks (e.g. title blocks), notes, lists, revision information, view states, restriction

notices, and the use of optional or supplemental blocks (see related term “Drawing Format”).

(1) 3D native models.

(2) 2D drawings derived from the 3D native models.

(3) 3Di PDF viewable data derived from the 3D native models.

merging of two ISO standards:

 Automotive's STEP ISO 10303-214, Industrial Automation Systems and Integration –

Product Data Representation and Exchange – Part 214: Application Protocol: Core

data for automotive mechanical design processes.

Digital data standardization should be specified when:

a. The potential for reuse of data exists; reuse may not be the same as for reviews or

other occasions to "revisit" the data.

b. A need exists for interoperability of standardized data among NASA Centers and

programs/projects with contractors, industry, partners, academia, services, and platforms.

c. The need to provide relationships between data for performing program/project

management, systems engineering, and operational functions exists.

An acquisition framework creates the foundation and baseline from which all other collaborative

MBE projects and programs should be driven. Interoperability and collaboration between NASA

(and their Government Centers and JPL) and commercial program partners is a daily event, and

the need for an updated process for dealing with digital data is required.

It is critical and incumbent for the program/project to review, redefine, and reuse current and

applicable NPRs as well as handbooks and collateral, including, but not limited to, DRDs,

PDLM, and systems engineering to accommodate model-based sharing and milestone delivery at

KDPs in Pre-Phase A through Phase F.

The collaboration framework is being driven not only by NASA standards and needs but also by

leveraging commercially defined leading and best practices. The goal is optimum model

exchange definition with consideration for current to trending Government and industry needs.

Guiding principles for data collaboration include:

a. Data as an essential enabler should be made visible, accessible, and understandable to

any potential user as early as possible in the program/project’s life cycle to support project and

mission objectives as constrained by security and access needs.

b. Data assets should be made visible by creating and associating metadata (“tagging”),

including, but not limited to, discovery metadata, for each asset.

c. Developed metadata standards should comply with applicable national and

international consensus standards for metadata interoperability; all metadata should be

retrievable using the NASA Centers’ systems with requirements to access the metadata.

d. Data assets should be accessible by making data available in shared spaces; all data

assets should be accessible to all users at the NASA Center except where limited by law, policy,

or security classification.

e. Data that is accessible to all users at the NASA Center should conform to that

Center’s specified data publication methods that are consistent with the Center’s current and

planned information systems capabilities.

f. To enable trust, data assets should have associated information assurance and security

metadata and an identified authoritative contractor and/or Center-level source for the data.

g. Data interoperability should be enabled through business and mission processes

reusing the Center’s information system capabilities.

h. Semantic and structural agreements for data interoperability should be promoted

through communities consisting of data users (producers and consumers) and system developers.

i. Data interoperability concepts and practices should be incorporated into education

and awareness training and Center-level processes.

j. Programs/projects should acquire the minimum essential contractor-originated data

required to meet all program/project life-cycle requirements.

k. Program/project managers and delegated Technical Authorities should consider data

requirements for future procurement needs in a manner that fosters competitive procurement

opportunities.

Three process domains require initial focus for MBE process interoperability:

a. Data collaboration (the definition and management of data, including models,

requirements, CAD parts, CAD model libraries, and other mechanisms that contribute to a

complete and valid design through design, development, test, and evaluation (DDT&E)).

b. Engineering release (the very beginning of design data CDM where engineering

designs are created, checked, and status is reported).

c. Integrated product structure (the core mechanism around which the relationships

between detail product design elements are defined).

Processes are to be implemented concurrently, authorized via institutional mechanisms such as

NPRs and standards, and used as expected by trained and supported end users.

Process interoperability also involves inventorying existing mechanisms such as currently

deployed capabilities and other application systems (e.g. approved parts list may be in another

database), locally approved processes, and the expected practices articulated in project plans,

contractor practices, or external standards called out in contract language.

Centers have their own documents and implementations inside systems of these processes, and

there may be multiples of each. So, interoperability must be addressed to:

a. Elaborate on the definition of the process domain.

b. Eliminate or reduce risk as a main thrust of collaborative decision making.

d. Collect data on the current state of things—who has what solutions in place now, in

what form, how extensive, what problem does it attack, are they usable outside of any given

Center, what is their effectiveness, etc.

desired outcome in a solution-independent way.

D.4 Digital Collaboration Framework and Environment

Data today is generally electronic; and as the design environment continues to move toward a

models-based approach, engineering/acquisition processes are more automated and demand a

highly collaborative/social workforce during all phases of the life cycle for effective utilization

and collaboration of MBE information (i.e. model-based “DATA”—Design and Definition,

Systems Engineering, Simulation and Test).

Additionally, with the advent of digital definition and the ability to annotate these model-based

artifacts, non-graphical definition can be represented in the model definition and can include:

a. DRDs for collaboration governance, contracts definition, and enforcement to properly

define KDP deliverables per contracted levels and per interoperability definition and

expectations.

b. Safety and Mission Assurance (SMA) problem reporting and corrective action,

hardware screening, reliability, failure mode and effects analysis/critical items lists, etc.

c. Operations, when the system is on-orbit operational and mission operations needs

access to the authoritative data.

d. Management oversight and awareness when management needs access to the

dashboard to see if any trends were previously identified.

e. Software interoperability with the ability to insert new software modules and the Data

Architecture allow for software upgrades while maintaining configuration.

f. Common data schema.

g. Standards-based-driven requirements.

h. Configuration and data management of the models to ensure data integrity and model

validation.

i. Risk and risk mitigation.

867-9209.

148 of 217

The collaboration framework addresses the acquisition and storage of all program/project data,

including the following:

a. Product/program definition.

b. Data collaboration framework (from acquisition through retirement).

c. Data definition (model-based design for “x,” where “x” represents different artifacts).

d. Systems engineering.

e. Requirements management.

f. Mechatronics management.

g. CM.

h. Engineering revision and version control.

i. Risk management.

j. Other artifacts developed within the product life cycle.

The data definition principles require aligning the organizational governance model and the

technology, taking into account the following scenarios and guiding principles:

a. Today’s product data requires special handling due to its dependence on technologies

such as system modeling (SysML™) and 3D CAD.

b. Product data is created and usable in different forms (lightweight and native) by

different communities across the full product life cycle.

c. Minimizing the building of custom solutions and customizing out-of-the-box software

and rely on external standards and configurability.

d. NASA standards for naming and CDM are followed to ensure proper DRD

compliance, expected search and capture results, and effective communication.

e. Institutional knowledge is leveraged from MBE implementers across NASA and their

ecosystem to provide a consistent approach to MBE.

D.5 Collaboration Definition and Environment

Collaboration should consist of a virtual development environment that allows immediate,

secured access to all product data via light-weight visualization tools. Without effective

collaboration, team members who are not co-located are forced to share documents using e-mail,

zip files, and/or a shared server; use multiple tools for collaboration that could manipulate the

native format or that could transfer insufficient product information; and always search for the

latest version of record.

The MBE collaboration environment creates a development environment that represents all types

of “digital” data, including, but not limited to, specifications, requirements, analysis results, and

legal entities, and instills a flexible discipline-enabling access to the right information at the right

time to the right people. The MBE collaboration environment, when leveraged and deployed

correctly, can have a major impact on mitigating risk, reducing cycle time, improving quality,

and ultimately, cost savings. It also allows for a quick and robust way to make decisions while

not incurring any cost on physical prototypes or models. In the end, it is a means toward

reducing risk by aiding the decision-making process.

Organizations embracing an MBE collaboration environment vision define the following four

themes as what makes or breaks a successful execution:

a. Integrity of the data—having the latest and most correct data from the onset

(whether internal or within the contracts that define the exchange of information). The data have

to be complete as well as consistent, making sure that the right information is available. DRDs

will define the level of depth and detail needed, as well as how that information can be

exchanged to ensure integrity is enforced.

b. Virtual access anytime/anywhere—global sharing, including security and

safeguarding of data, as well as supply chain enablement, is critical to handling complex systems

from both a push and pull perspective as part of operational workflow. This capability is critical

for operations such as engineering release or change management, making sure the data is

available at the right time to the right people. The completeness and integrity of the data and

ability to access information 24 hours, 7 days a week are expected.

c. Discipline in integrated product definition-driven development—stemming from

the integrated product structure, including options and variants. Once the structure is defined,

management of configurations and changes needs to be scalable as well as enforced.

d. Visualization—just beginning to be referred to as “virtualization”—using light-

weight and intelligent visualization software that is capable of total product representation and

animation for form and fit decisions, analysis, management, and assembly.

Successful product development for NASA relies on some key capabilities as follows:

a. Visibility and management of requirements throughout the product development

process.

b. Access to a more complete “data model” at any time during the development process

that represents an intelligent and fully defined artifact versus an amassing of multiple documents

from remote resources.

c. More informed decision making for the appropriate selection of design strategy.

d. Ability to better leverage and enable the different program/project levels and primes

by bringing them closer to the product development life-cycle phase and decision process.

e. Ability to reuse products and processes and incorporate new requirements as

needed/when needed.

f. Flexibility for domain autonomy built into product design and manufacturing

processes.

g. Validation of functional product and process capability to ensure that products meet

the needs of the Agency and that processes work effectively.

While MBE can provide value and help achieve some of these technical goals, it will not be

totally successful without changes in many domains. Development of an MBE collaboration

environment is essential in fully achieving these goals. As a part of executing an MBE

collaboration environment strategy, desired data end states have to be converted into more

specific objectives as follows:

a. Pre-release Data Sharing—

(1) When serving as systems integrator, engineering data have to be shared with other

engineering groups, including to and from primes, prior to formal engineering

release.

(2) Vertical data movement (e.g. downward for requirements, upward for analysis

results) supports decision making but does not support the horizontal and diagonal

flow of data, especially CAD and other specialized data. The question was how to

keep track of which version of the model was used and for what.

(3) Today, if a problem is found in that model, the capabilities to share such data may

outstrip the organizational capacity to facilitate and monitor it. MBSE, along with

M&S, does a very good job of defining the infrastructure that defines access and

what is required to answer many of these questions; but it is the MBE

collaboration environment framework (as defined by the other initiatives) that

makes the access and sharing possible.

b. Distributed, Non-Document-Centric Authority—

(1) Product structures and designs are just some of the data managed in systems.

They cannot serve their purpose if the electronic version is not authoritative.

867-9209.

151 of 217

(2) On many projects, authority for design is distributed unequally: the number of

data objects to be reviewed and approved increases non-linearly as one goes

DOWN the product hierarchy.

(3) Furthermore, the distributed vehicle elements are simultaneously in different

design states; highly distributed authority combined with the interlinked data

structures of CAD complicates the dynamics of intra-element flow of design data.

c. Process, Tool, and Use Synchronization—

(1) In an MBE collaboration environment, the processes and workflows are

implemented in the tool suite and provide real value when they are actually used.

(2) The engineering release definition, as well as NPR 7123.1, defines this model;

and MBE can act as the framework to ensure that the right data is available at the

right time.

d. Handling Data Objects—

(1) The larger picture of significant design data being created by primes and partners

really shines a spotlight on scalability and usability challenges experienced today

around handling objects within MBE environments. Definition of the need for the

model and its attributes is blurred; therefore, native data (which can be very large

in itself) carries a lot of unnecessary baggage that will never be used by the

recipient.

(2) New ways of thinking are needed about what it means to make a “delivery,” to

“receive” and/or “use” a model (or representation), which then needs to be

properly reflected in the DRD clause, to “release” a design, and how to deal with

ownership, change, and configuration control around complex data entities that

are still actively being defined and do not behave like PDF files or drawings.

e. Having a Voice—

(1) NASA has dynamic needs because the mission is research, science, and

exploration. The mission is to do things that have not been done before.

(2) When processes are linked to tools and one cannot do the job without the data that

is in them, a move toward processes enabled by technology is necessary:

A. Who gets to decide on the requirements for the application?

B. Who gets to influence the decision on the trade analysis results?

C. Who gets to move their problem to the top of the “to do” list?

(3) Governance has to recognize the needs of different users to be heard at different

times, and the infrastructure has to support it.

f. Data Usability and Collaboration—

(1) Capability deployment that maps to defined user communities. Achieving this

landscape will require both technical and process solutions to be designed, built,

configured, tested, deployed, used, and supported.

(2) Additional attention to enable the move from document centricity to data will

require focus on new practices, including contract language (DRD clauses) and

supporting tools, around specification of technical data packages, and the conduct

of CDM.

D.6 Collaboration Planning and Development

MBE is a critical element with technical and programmatic implications. Management at the

Agency, Mission Directorates, programs/projects and their delegated Technical Authority(s)

have the responsibility to determine the following at their respective levels:

a. How much should be risked (or how much should the program/project pay) to ensure

the relevant data exist and are accessible, discoverable, and understandable to support such

events as some in-flight anomaly 10 or more years in the future?

b. Where should the Agency and the program/project invest their limited attention and

resources on data during the development cycle?

The MBE Plan (refer to Appendix J for guidance in developing the Plan) documents the

foundation for these decisions. The program/project managers and the delegated Technical

Authority(s) sign and release the Plan prior to the completion of the System Definition Review

(SDR). A program/project’s compliance with NPR 7120.5 is verified by submission of the initial

preliminary Plan. A program/project manager and the delegated Technical Authority(s) require

support in the development of the strategy and the Plan.

The Program Manager and delegated Technical Authority(s) are responsible for documenting in

the MBE Plan the scope of each Center's responsibilities and partner/prime or supplier

requirements for collaboration, including:

a. The implementation approaches.

b. The environment in which the program and its projects' MBE solution(s) operates.

c. The level of digital maturity required for decision enablement and effective passing of

digital information.

d. The timing for implementation of the MBE solution and associated processes, data,

elements, attributes, and formats.

APPENDIX E

ARCHITECTURE

E.1 PURPOSE

Collaborating within and outside NASA will be greatly enhanced through digital and model-

based methods. This Appendix provides guidance for a consistent architectural framework,

which is necessary to ensure compatibility.

E.2 MODEL-DRIVEN ARCHITECTURE

The OMG initiative defines model-driven architecture (MDA), which is leveraged by several

standards such as Meta-Object Facility, XMI, common warehouse metamodel (CWM), Common

Object Request Broker Architecture (CORBA), and Unified Modeling Language (UML). The

former approach relied on Executable UML and Object Constraint Language (OCL) instead, and

query/view/transformation (QVT).

MBA’s "eco-system" of programming and modelling tools are represented in general terms by

the Eclipse Modeling Framework. This framework allows the creation of tools implementing the

MDA standards of the OMG; but, it is also possible to use it to implement other modeling-

related tools.

NASA believes that existing standards do not provide sufficient resolution to create collaborative

models; therefore, the establishment of an Agency-level collaborative environment and

architecture is critical for program success. Other NASA Technical Handbooks will be

developed to reflect more information toward recognizing and implementing the appropriate

architecture.

Discussion goes deeper and reviews the implementation of MBE requirements for the

establishment of Agency-level collaborative environment types. Implementation of MBE

requires the establishment of an Agency-level collaborative environment and architecture

defined as four types of architectures:

a. Security.

b. Information Support System.

c. Data.

d. Process.

E.3 Architecture Rationale

Collaborating within and outside of NASA will be greatly enhanced through digital and model-

based methods. A consistent architectural framework is necessary to ensure compatibility.

Existing standards do not provide sufficient resolution to create collaborative models.

In accordance with the life cycle in NPR 7120.5 (with tailoring for projects less rigorous than a

flight project), the life cycle for this activity follows:

a. Pre-Phase A: Define the mission and study multiple approaches to the framework.

b. Phase A: Define top-level architectural framework requirements and select a single

approach.

c. Phase B: Complete architectural framework requirements and perform preliminary

design of architectural framework.

d. Phase C/D: Complete and build the framework.

Goddard Space Mission Architecture Framework (GSMAF) follows ISO/IEC/IEEE 42010 and

other community standards such as NPR 7120.5 and NPR 7123.1. GSMAF is structured to

address needs and concerns of primary stakeholders for Goddard Space Flight Center science

missions:

• Science Viewpoint – What do the Principal Investigator and Science Team care

about?

• Systems Engineering Viewpoints – How do we design, build, and test “The

System?”

‒ Requirements – What are the necessary and sufficient aspects of the product(s)

that will execute the Mission?

‒ Product Design – What are the definition/designs of the product(s) elements

necessary to execute the Mission?

‒ Realization Viewpoint – How do I build, integrate, and test the product elements?

• Management – How do we manage a team and resources to design, deliver, and

operate the product(s) to execute the Mission?

‒ Project Development Viewpoint – What are the project schedule, budget, risk,

resources, and organization required to define and deliver the product(s)?

‒ Operations Viewpoint – What are the plans, rules, and procedures for “Mission

Operations?”

 Enterprise Viewpoint – How does the effort currently align with programmatic and

institutional policy, direction, reporting, and resources?

E.3.1 Security Architecture

The Security Architecture exists to ensure continuity of Mission Directorate operations for both

flight projects and ground operations through the management of risks and vulnerabilities to

protect humans, flight and ground facilities, information, systems, and services against disasters,

threats, errors, and manipulation.

The Security Architecture is a collection of components or layers of security that provide

information assurance. These include policy and security management, application security, data

security, platform security, network and perimeter security, physical security, and user identity

security. It provides the program/project with reliability, quality, integrity, availability, and

confidentiality of data and systems in compliance with Federal and Agency regulations and

requirements.

It is the responsibility of the Agency CIO to develop the Security Architecture as defined in

NPR 2800.1, Managing Information Technology, and NPR 2810.1.

The program/project managers and the NASA Chief Engineer, or delegated Technical

Authority(s), have the responsibility to ensure that appropriate IT elements and approved IT

security plans are in place and address the elements as required by their Center-level procedural

requirements documents.

E.3.2 Information Support System Architecture (ISSA)

The ISSA is comprised of IT components allowing users to access all model-based definition

data under a configuration-managed, secure environment. The ISSA allows programs/projects to

capture, integrate, and manage product and process information from diverse authoring

applications in a single environment.

This MBE environment enables the definition and standardization of workflow-driven processes

that can be leveraged and used across multiple programs/projects. The ISSA is designed to

integrate multiple mission-critical systems through the use of industry standards in MBE (e.g.

open application programming interfaces [APIs] and enterprise service buses) to aggregate and

extend knowledge sharing throughout the organization. It is the responsibility of the Agency CIO

to develop the ISSA.

The Agency CIO has the responsibility to ensure that IT and information resources are acquired

and managed in a manner that implements the requirements, procedures, and priorities defined

by NPR 2800.1 and ensure that IT products, services, and information systems meet customer

and stakeholder requirements.

E.3.3 Data Architecture

A Data Architecture describes how data are processed, stored, and utilized in a given system or

product definition. It provides criteria for data processing operations that make it possible to

design data flows and also control the flow and association of data in the system. If

programs/projects do not have the Data Architecture from the start, the program/project data

becomes disorganized quickly and is nearly impossible to electronically integrate or discover as

the level of data increases over time.

The Data Architecture provides for creation, storage, and exchange of data, especially PDD,

models and simulations, and for the requirements imposed on the MBE solution elements to

support data interoperability, management, integration, metadata, and work practices, including,

but not limited to, standardized taxonomies and ontologies, and should be based on common,

open standards or NASA standards.

The Data Architecture processes and requirements have to be flexible to accommodate changes

in MBE vendors, NASA Center and institutional software, and environments and allow the

inclusion of external suppliers or partners that use their own local MBE environment or do not

currently support an MBE environment.

The CIO provides the infrastructure/systems for implementing an architecture that supports the

creation, storage, interoperability, and exchange of data. Engineering defines the program/project

data that the architecture has to support and the criteria for data processing operations, data

flows, and the association of data in the system. Further, engineering supplies the requirements

for the infrastructure/systems needed to meet these criteria. The program/project manager and

delegated Technical Authority(s) are responsible for ensuring that the Data Architecture meets

the program/project’s needs. The program/project Data Architecture should be defined and

documented in the MBE Plan.

E.3.4 Process Architecture

Processes enable the integration of diverse human and systems activities to coordinate the

exchange of services and data/information, including process design, process execution, and

process monitoring. A Process Architecture is a description of the program/project business

processes. The Process Architecture establishes standards in how the program/project will create,

manage, and control program/project data. A Process Architecture describes data interoperability

requirements at defined life-cycle states and maturity levels (both internally and externally to

NASA); describes which processes will be applied across all projects (e.g. safety and mission

assurance, deviations and waivers, corrective actions, and problem resolution); and identifies the

source for documented common nomenclatures and schemes for product naming, numbering,

and version control.

The MBE Process Architecture defines flow of the program/project data, the roles and

responsibilities for data handling, and the approval authority. The Process Architecture should

clearly define, control, and integrate business and engineering processes for program/project

execution based on results from life-cycle cost analyses. Processes should be subjected to value-

added analysis techniques (e.g. streamlined, efficient, effective processes) prior to

implementation. A well-defined Process Architecture will ensure that every person or

organization involved executes the process. Each process to be used is fully documented so that

everyone understands their respective involvement in the process.

The program/project manager and delegated Technical Authority(s) are responsible for defining

the relationship between businesses and engineering processes and documenting these

relationships in the MBE Plan. The Agency CIO and applicable Mission Directorate are

responsible for implementing the requirements of the Process Architecture

If established early and properly, the key benefit of the MBE Process Architecture is that all

program/project team members will clearly understand data control and release, including which

data are authoritative and the process through which the data are released to become

authoritative.

APPENDIX F

INTEROPERABILITY STANDARDS

F.1 PURPOSE

This Appendix provides guidance for establishing the proper data interoperability capability. In

recognition of adopting a true collaborative MBE environment, NASA needs to adopt industry

standards and approaches for digital data interoperability, which will enable data interoperability

and move beyond the storage of raw, uncorrelated data.

The true benefit of a model-based environment may not be seen at the Center or authoring level;

however, upstream and downstream users are hugely impacted as the amount of work required to

validate or modify the completeness or correctness of the data being shared increases. NASA-

STD-7009, Standard for Models and Simulations, provides requirements for determining the

credibility and integrity of model-based results and model application.

Furthermore, a model-based environment as part of an MBE strategy also covers the integrity

(security, relationships, revision currency, effectivities, interoperability, standards compliance,

etc.) of the data.

F.2 INTEROPERABILITY

Table 5, System and CAD Model Interoperability Insights for Project Data Acquisition and

Exchange, illustrates use of data in a models-based environment, in particular for 3D CAD

interoperability, and how to facilitate better planning and acquisition of design data.

F.3 Exchanging and Distributing Models

To ensure data transportability and integrity, the need for NASA to adopt industry standards and

approaches for digital data interoperability is required to enable data interoperability and move

beyond the storage of raw, uncorrelated data.

Proper data interoperability capability is only achieved through the identification of IT standards

and the application of contractual methods to ensure implementation and alleviate the data

interoperability limitations that currently challenge NASA’s programs/projects.

Multiple options for data interoperability among NASA Centers and programs/projects with

contractors, industry, partners, academia, services, and platforms exist. For example:

 CAD systems are all moving toward 3D digital formats as their means of the

authoritative source and definition. Exchanging 3D data within engineering

departments, between primes, and with other divisions and departments is critical to

program/project development; however, not all of these use the same CAD system.

 When parts are developed in 3D, the data is initially stored in the original format in

the authoring system (or PLM) of the software used to design the part; but, when the

need to share/collaborate occurs, a neutral 3D format is necessary. (Refer to NIMA-

RPT-004). In general, a neutral 3D format as the medium for collaboration should be

selected.

Note: The program/project manager and delegated Technical Authority(s) have the

responsibility to identify and acquire essential contractor-originated data with sufficient access

and usage rights to support not only the full program/project life cycle, but also the enterprise

needs of the Mission Directorate and Agency as a whole. Contractor data interoperability is

achieved through identification of IT standards and guidance on contract language.

F.4 Standards

Table 4 illustrates use of data in a models-based environment, in particular for 3D CAD

interoperability and how to facilitate better planning and acquisition of design data.

F.5 Model-Based Engineering Standards Elements

The well-defined MBE environment should:

a. Host the library used for authoritative (x) CAD designs.

b. Provide a distinguished security and access model for the libraries that restricts all

changes to a designated set of librarians.

c. Provide efficient mechanisms for managing large families of similar items.

d. Prevent or reduce the occurrence of duplicate or multiple part numbers and

designations for an identical physical device; a part number should map to a specific, unique set

of specifications.

e. Address the maintenance of additional metadata for standard parts such as standard

identifiers, extensions for tracking the configuration of mission sets, and effectivities which map

revisions/versions to the extensions.

f. Manage the parts data developed by the design organizations developing the product.

g. Allow for inclusion of new libraries and mechanisms as new organizations enter the

environment, new suppliers are added, and parts suppliers are consolidated or removed from the

marketplace.

h. Provide for library availability for the required life cycle of the program/project.

i. Host the library used for requirements development and requirement-to-part

associations.

F.6 Industry Standards for Data Interoperability

Table 6, Target Industry Standards for Data Interoperability Formats, provides guidance for

industry standard data interoperability formats that are well suited for relational and object model

data interoperability implementations at the time of this document’s release. For reference

documents, see Appendix K.

The interoperability formats in Table 6 are based on the World Wide Web Consortium (W3C)

Internet Standard: XML and supporting protocols. These standards are specific to the applicable

data interoperability formats in maturity level 3 in Table 8.

Note Standard Definitions:

XML: XML is a simple, very flexible text format derived from Standard

Generalized Markup Language (SGML), ISO 8879, Information processing – Text

and office systems – Standard Generalized Markup Language (SGML). Originally

designed to meet the challenges of large-scale electronic publishing, XML is also

playing an increasingly important role in the interoperability of a wide variety of data

on the Web and elsewhere.

Namespaces in XML: XML Namespaces

are a simple and straightforward way to

distinguish names used in XML documents. XML Namespaces provide a simple

method for qualifying element and attribute names by associating them with

namespaces identified by Uniform Resource Identifier (URI)

references.

XML Schema: XML Schemas (per XSD) express shared vocabularies and allow

machines to carry out rules made by people. They provide a means for defining the

structure, content, and semantics of XML documents in more detail.

OMG XML Metadata Interchange (XMI): The main purpose of XMI (ISO/IEC

19503, Information technology – XML Metadata Interchange (XMI), is to enable

easy interoperability of metadata between application development life-cycle tools

such as modeling tools based on UML (ISO/IEC 19501, Information technology –

Open Distributed Processing – Unified Modeling Language [UML]), and metadata

repositories/frameworks based on the Meta Object Facility [MOF]) (ISO/IEC 19502,

Information technology – Meta Object Facility [MOF]), in distributed heterogeneous

environments. XMI integrates the following three key industry standards:

a. XML.

b. UML, an OMG modeling specification (ISO/IEC 19501). (Note: XMI is

expressed as UML and is listed here for completeness.)

c. MOF (ISO/IEC 19502).

5. STEP Application Protocols (APs): "Standard for the Exchange of Product (STEP)

model data for systems engineering" or ISO 10303 "Industrial automation systems

and integration — Product data representation and exchange," contains various APs.

The STEP APs (e.g. ISO 10303, Part 209; Part 210, Industrial automation systems

F.7 Interoperability and Sustainability

Program/project managers and delegated Technical Authorities are responsible for determining

the MBE interoperability and sustainability requirements and ensuring these are identified across

all participating organizations and in all program/project contracts. Inclusion of international

partners could have a different set of interoperability and sustainability requirements that would

need to be addressed. The following provides guidance to assist with the development of these

requirements.

APPENDIX G

USE CASES FOR ESTABLISHING MBE ELEMENTS AND

INTEROPERABILITY REQUIREMENTS

G.1 PURPOSE

This Appendix provides four use cases to consider when establishing MBE elements and

interoperability requirements in correlation with Table 6. Understanding neutral format data

usage allows for the appropriate tools to be selected in the most cost-efficient manner, efficient

data exchange mechanisms to be established, and for everyone requiring data access to have that

access at the required level.

G.2 USE CASES

The use cases are defined as follows:

a. Viewing:

(1) If the use of a CAD system is not desired, the visualization of engineering data

using 3D viewers comes into play in a number of different situations: the

presentation of product data, the representation of 3D models for information

purposes (e.g. for a design review or marketing), and the realistic representation

in virtual reality systems.

(2) While the simple viewing of the geometry is sufficient in many cases, in other

cases, metadata or PMI also needs to be displayed.

(3) The high-performance visualization of large assemblies or design spaces and

neighboring geometries is often an important criterion.

(4) In cases such as these, it is especially important that simplified representations are

used.

(5) The most important needs for simplified representations are:

A. The source system-independent representation of the model data (geometry

and metadata) with the required level of detail.

B. The ability to filter the product structure (e.g. using views or layers).

C. The execution of simple measurements.

D. Representation of PMI.

E. The ability to represent textures and sources of light for applications in the

area of virtual reality.

F. The availability of easy-to-use, cross-system viewers.

867-9209.

169 of 217

b. Data Exchange:

(1) In development processes, it may be necessary to exchange exact geometry

between different authoring systems such as requirements or CAD systems. This

is, for example, the case if a supplier is using a different CAD system than the one

used by the manufacturer.

(2) Another common situation is that one of the development partners makes a

change to the geometry after it has been exchanged. In this case, merely viewing

the data is not enough. What is needed is a typical and frequently used modeling

method involving design in context of existing geometry defined as follows:

A. When exchanging exact geometry, additional information describing the

product is often needed. In this context, a distinction is made between PMI

and metadata. While metadata refers to descriptions that consist only of text

(e.g. information about the author or the release status of a model), PMI is

often added in the form of 3D annotations, manufacturing notes, and material

specifications.

B. This makes a greater demand on the underlying data format and on the

application doing the processing. Grouping and filter options are needed to

ensure clarity.

C. Another frequent requirement is that the processing of PMI be possible

subsequent to data exchange. The protection of intellectual property is also

playing an increasingly important role in data exchange, and it should

therefore be possible to take this aspect into consideration and reflected

properly in the DRD.

(3) The most important items to be considered are:

A. The data format and collaborative model definitions to ensure the transfer of

exact geometry and the entire product structure.

B. The transfer of metadata, as well as PMI annotations (depending on the

technical readiness level (TRL) being executed and where a concrete use case

is involved).

C. Ensuring data integrity, fidelity, and completeness, and one-to-one correlation

between the original model and the target model.

c. Data Integrity:

(1) Programs/projects are formulated and implemented following various NASA

directives through multi-disciplinary teams of engineers and other personnel, with

systems engineers, program/project managers, and delegated Technical

Authorities working across the other engineering disciplines to achieve integrated

systems on schedule and within budget throughout the program/project life cycle.

(Refer to NIMA-RTP-002, Data Integrity in NASA Programs and Projects

(2) A primary use of this data is for making informed decisions by individuals and

teams, including decisions made at life-cycle reviews involving the evaluation of

various aspects of the program/project. In each of the life-cycle phases and

reviews, these multi-disciplinary teams work with a multitude of data related to

the systems being developed, including requirements, verification requirements,

test verification requirements, failure modes and effects, risks, hazards, and

problem reports, among others, and are often linked to each other. In operations,

the data becomes critical for determining the readiness of the systems, with the

consequence of poor data integrity having potentially catastrophic effects,

including loss of mission.

(3) Two major forms of data integrity have been identified as follows:

A. Integrity of Data Relative to its Authoritative Source

i. Integrity of data relative to its authoritative source is defined by the field

of information security as the property that data have not been changed,

destroyed, or lost in an unauthorized or accidental manner. In the context

of NASA programs/projects, the most common and actionable form of this

is the integrity of data relative to its authoritative source across and within

a program/project.

ii. Within programs/projects, authoritative sources exist for various types of

data involving, in many cases, the use of various discipline-specific tools

and varying instances of the same tool. To conduct integrated analyses and

reviews using data from one or more disciplines or from one or more

tools, data from authoritative sources need to be integrated. The common,

current practice is to manually copy data from its authoritative source into

other tools, documents, or presentations. From the moment the data is

copied out of its authoritative source, a risk that the data is out of date

exists, as changes to data in the authoritative source are not automatically

made in the manual copy; the integrity of the data from the perspective of

the authoritative source may be compromised. Existence of data

discrepancies presents a high probability program/project risk of incorrect

decisions being made, inadequate integrity of the program/project

integrated design being represented, or inadequate readiness of

programs/projects and their associated systems being presented.

The referenced white paper NIMA-RTP-002, Data Integrity in NASA Programs and Projects, traces requirements

for data integrity to NASA Procedural Requirements and describes how data integrity is a critical factor for

achieving integrity of the program’s integrated design, as well as the readiness of the operational flight and ground

data systems. It also provides data management lessons learned.

867-9209.

171 of 217

B. Integrity of Data Relative to an Authoritative Model

i. Integrity of data relative to an authoritative model is defined by the field

of database systems as the property that data are an accurate reflection of

the domain of discourse it is attempting to model. In the context of

NASA programs/projects, the most common and actionable form of this

is the composite and component integrity of data relative to an

authoritative model.

ii. Authoritative models of valid forms of data exist, from a single piece of

data relative to the model of a valid data type, range of data, or simple

text rules (component data integrity), to more complex data involving

multiple pieces of data relative to each other and an authoritative model

(composite data integrity).

iii. The primary solution for improved data integrity is the use of information

systems to change from manual processes of data integration and

validation to automated processes.

(4) Two main approaches, automated data integration and automated data audits, are

addressed as follows:

A. Automated Data Integration Relative to Authoritative Sources of Data

i. Goals of using this approach include improved data integrity and data

accessibility and elevated efficiencies in data management over the full

program/project life cycle.

ii. Lack of data integration has been identified as leading to cost and risk

increases due to use of non-authoritative/out-of-date data,

miscommunication of data, and missing data. With this approach, use of

non-authoritative copies of data is minimized through automated data

aggregation. Consequently, rates of engineering data discrepancies are

also reduced whenever automated data aggregation is used. User

communities can manage specific data in tools explicitly designed for the

management of that data and can also implement specific processes that

integrate data directly from the authoritative sources into reports and other

formats.

B. Automated Data Audits

i. Performing automated audits using information systems is a proven

approach that has high utility and relatively low cost.

ii. In the engineering realm, data audits can be performed daily or weekly to

help drive convergence in design, and can serve to ensure the integrity of

the data that is used in baseline versions of a multitude of engineering

artifacts. This can be done at the elemental level with a single piece of

data, or at the composite level with multiple pieces of data.

d. Data Interoperability Formats:

(1) Data interoperability refers not only to CAD data but also to non-CAD data used

in innovation and preliminary designs and other pre-CAD domains (e.g.

requirements analysis). All formats need attention and are considered part of

digitalization. All data interoperability should follow standards where applicable

(e.g. STEP, XML):

A. Requirements interoperability should focus on STEP AP 242, 239, 233 in ISO

10303 and also follow Regulated Qualifications Framework (RQF) or

Requirements Interchange Format (RIF) standards.

B. CAD data interoperability formats should be chosen based on the need for

interoperability or reuse after delivery.

(2) Currently, MCAD data formats may be selected from Table 6. In Table 8, Format

Maturity Levels, a maturity level is assigned to each data format by which the

dynamics of each can be judged against intended utilization. (Refer to NIMA-

RPT-004.) However, users should assess the current trend in technology from

other sources prior to selecting data interoperability formats.

Specify when reuse and/or life-cycle maintenance of materials is not desired.

Note: This approach is not recommended nor supported under MBE.

B. Level 2 (Formatted Documents)

Documents delivered electronically in a customer-approved, contractor format

but containing no attached electronic semantic meaning. This approach is not

recommended nor supported under MBE. Specify when standard digital data

can be delivered as electronic paper in a digital form. Electronic paper should

include metadata tags, including, but not limited to, data type, system, title,

and last modified to assist with document identification, storage, indexing,

and key word tagging down to a minimum of three levels of subsections as

defined by the program/project. Reuse and/or life-cycle maintenance of

materials is not desired.

C. Level 3 (Standard XML Data Descriptions for Digital Data in NASA Standard

Format):

For standard XML digital data descriptions to be usable, a common data

dictionary has to be referenced by all producers and consumers of digital data

as defined by NASA’s common data dictionary. If a NASA standard is not

applicable, digital data has to reference a common data dictionary as defined

by the contractor. A catalog of XML schema data descriptions should exist

prior to the delivery of contractor data to NASA. Specify when:

i. The potential for reuse of data exists.

ii. A need exists for interoperability of data described by XML schemas

that move between/among NASA Centers and programs/projects with

contractors, industry, partners, academia, services, program/project

life-cycle states, and/or platforms.

iii. Tagging data according to law, requirements, and classification is

needed at the data object level.

D. Level 4 (Digital Data from a Source Repository to a Target Repository in a

Program/Project-specified Format):

Zip is a file format used for data compression and archiving. A zip file contains one or more files that have been

compressed, to reduce file size, or stored as is. The zip file format permits a number of compression algorithms. Zip

files generally use the file extensions ".zip" or ".ZIP.”

Digital data extraction from a source data repository in supplier format, data

transformation into a target format, and data loading into a target data

i. The potential for reuse of data exists.

ii. A need exists for interoperability of standardized content

between/among NASA Centers and programs/projects with

contractors, industry, partners, academia, services, program/project

life-cycle states, and/or platforms.

iii. A content interoperability management system that conforms to an

existing or planned set of NASA information systems and data

capabilities that can receive the content.

iv. A need exists for interoperability of database repositories

between/among NASA Centers and programs/projects with

contractors, industry, partners, academia, services, program/project

life-cycle states, and/or platforms.

v. A database-to-database integration approach exists.

vi. Tagging data according to law, policy, or classification is needed at the

data object level.

(4) Minimizing customization and adapting external standards can reduce the

complexity and would facilitate future upgrades and the exchange of data with

external parties. Because process definition is integral to MBE, the native tool

flexibility means that even a no-customization solution can still proliferate

complexity and inhibit data sharing.

(5) Consolidation of instances of PDM can reduce the visible number of systems

while doing little to achieve the critical goals of improved bi-directional sharing

of data internally and externally as stated below:

A. For instance, creation of multiple partitions within a single installation in

which each partition owner can reproduce their own processes, data structures,

and configuration settings will reduce the number of visible “systems” but not

guarantee data exchange.

B. Process terms include the definition of the data objects, the flow steps, the

descriptors, user roles, and the decision rules.

C. The processes are implemented by configuring elements into flows, so

agreement on the base elements is needed to facilitate data sharing and reduce

maintenance costs.

D. The depth of agreement on the base elements and flow configuration is the

primary mechanism by which interoperability can be achieved.

(6) In lieu of globally defined and rigid process definitions that have to accommodate

all types of work, the core definition of critical processes related to

interoperability should be pursued. By looking for commonality around

collaboration and data sharing, over-specification is avoided and adaptability is

encouraged.

(7) Managing product design and facilitating its use also depends on the design data

itself being compliant with a set of practices applied outside the tool. Most

notably, the configuration, accuracy, identification, and other settings enacted by

engineers within the same tool will affect the ability and effort required to share

their data with each other; a perfect MBE solution cannot overcome

incompatibility choices made at the source. The list of processes that need to be

discovered and assessed for interoperability begin outside the MBE tool and

extend into manufacturing, procurement, logistics, and mission operations

application and systems interfaces.

(8) A program/project manager and the delegated Technical Authority need to

address this list of questions that drives process interoperability:

A. How will peer engineers and designers be allowed to share data in support of

detailed design?

B. What is sufficient and necessary to define for a specific need (e.g. design,

verification, manufacturing):

i. Part (hardware and software).

ii. Assembly or subsystem.

iii. Systems or products.

C. How are parts identified and named to avoid conflict, confusion, and reduce

data redundancy?

D. What is the definition of models for a specific purpose (e.g. systems design,

part design, envelope, interface checking, thermal and structural analysis,

integration, and shrink-wrap)?

E. How are the alternate versions of models related and managed, and what is

required to ensure traceability and sharing?

F. What practices and resources reduce the effort required to find, use, and

integrate approved part definitions, including common hardware?

G. What state labels, descriptors, and process steps identify the allowed uses,

authorized user, and change status of engineering design data during its life

cycle (e.g. engineering release, change control, and configuration definition)?

H. What defines a product structure for a given use/audience/life-cycle state, and

how is that product structure produced and approved?

Authoritative Data: Data that have been designated as valid for specific official

programs/projects. The designated data is controlled by processes. (Source: NPD 7120.4,

NASA Engineering and Program/Project Management Policy)

Authoritative Source: An application or repository identified as the official source for

specific authoritative data.

Computer-Aided Design (CAD): Process of creating engineering designs defined by

electronically produced multi-dimensional geometry using special software systems, the tools

used by engineers to create geometric-based design definitions represented in a variety of

formats, including two-dimensional (2D) drawings, three-dimensional (3D) solid models,

envelopes, wireframes, and kinematics and time-based models.

Configuration Management (CM): A management discipline applied over a product's

life cycle to provide visibility into and control changes to performance, functionality, and

physical characteristics. (Source: NPR 7120.5, NASA Space Flight Program and Project

Management Requirements) Also, a technical and management process for establishing and

maintaining consistency of a product’s functional and physical attributes with its requirements,

design, and operational information throughout its life. (Source: SAE EIA-649, Configuration

Management Standard)

Contract Data Items List (CDRL): A list of authorized required data requirements for a

specific procurement that forms part of the contract/agreement. It is comprised of either a

single or multiple DRDs containing data requirements and delivery information. The CDRL is

the standard format for identifying potential data requirements in a solicitation and deliverable

data requirements in a contract. Use of the CDRL in solicitations is required when a contract

will require delivery of data. CDRLs should be linked directly to Statement of Work (SOW)

tasks and managed by the Program Management Office (PMO) data manager. Data

requirements can also be identified in the contract via Special Contract Clauses (e.g., Federal

Acquisition Regulations/NASA Supplements [NFARS]), which define special data provisions

(such as Rights in Data, Warranty, etc.).

The purpose of the CDRL is to provide a standardized method of clearly and unambiguously

delineating the Government’s minimum essential data needs. The CDRL groups all of the data

requirements in a single place rather than having them scattered throughout the solicitation or

contract. A DRD is the completed document that defines the data required of a

contractor/Offeror and is included in the CDRL. The DRD is used to specifically define the

data content, format, and intended use.

Data: The lowest level of abstraction from which information and knowledge are

derived. Any collection of recorded facts, numbers, or datum of any nature that can be

communicated, stored, and ultimately processed, using business rules, to form useful

information. (Source: SAE EIA-649)

• Authoritative source of truth (ASOT) - an entity such as a person, governing body,

or system that applies expert judgement and rules to proclaim a digital artifact is valid

and originates from a legitimate source. (Source: OMG.)

a. The ASOT for a digital artifact serves as the primary means of ensuring the

credibility and coherence of the digital artifact that its creators share with a

variety of stakeholders.

b. It gives stakeholders from diverse organizations and distributed locations the

authorization to access, analyze, and use valid digital artifacts from an

authoritative source.

c. The owners of digital environments or the community for digital engineering

ecosystems provides stakeholders with an authoritative source of truth that

assures confidence in the quality of the digital artifact across disciplines,

domains, and life-cycle phases.

• Single source of truth (SSOT)

• Architecture - practices structuring information models and associated data

schemas such that each data element is mastered (created and/or edited) in only

one/single location (no duplication of data or documentation)

a. Any/all linkages to a data element (in other locations within the

relational schema or in external federated databases) are by reference

only (pushed/pulled data resides in one source and will update

immediately upon source update),

b. Since all other usages of (locations) the data element merely refer to the

primary "source of truth" location, updates to that data element in the

primary location are subsequently propagated through the entire system

without possibility of a duplicate (non-referenced) value somewhere

being forgotten.

c. Organizations with more than one information system, wishing to

implement an SSOT (without modifying all but one master system to

more of three supporting technologies, namely:

Enterprise service bus (ESB), Master data management (MDM), or Data

warehouse (DW).

• Authoritative Source of Information/System of Record (SOR)

• A system of record is the authoritative data source for a given data element or

piece of information.

Data Architecture: Provides an understanding of what information is needed to

effectively execute the Enterprise's business processes and provides a framework for

effectively managing the Enterprise's information environment. Note: Data Architecture links

information behavior (i.e. accessing, using, and sharing data), information management

processes, and information support staff to other aspects of the Enterprise. (Source:

NPR 2830.1, NASA Enterprise Architecture Procedures)

Data Life Cycle: The series of states that a data object can take from its creation to its

retirement or destruction; generally, these states represent maturity levels or indicate suitability

for, or restrictions on, use.

Data Management: The process used to:

a. Provide the basis for identifying and controlling all types of digital and electronic

data.

b. Provide the basis for identifying and controlling data requirements and

specifications.

c. Responsively and economically acquire, access, and distribute data needed to

develop, manage, operate, and support system products over their product-line life.

d. Manage and dispose data as records.

e. Analyze data use.

f. Ensure data integrity, fidelity, access, security, and proliferation.

g. Enforce data definition standards (naming, security, revisions, CDM).

h. If any of the technical effort is performed by an external contractor, obtain

technical data feedback for managing the contracted technical effort.

i. Assess the collection of appropriate technical data and information.

j. Effectively manage authoritative data that defines, describes, analyzes, and

characterizes a product life cycle.

k. Ensure consistent, repeatable use of effective MBE processes, best practices,

interoperability approaches, methodologies, and traceability. (Source: NPR 7123.1)

Data Model: Identifies the data, their attributes, and relationships or associations with

other data. (Source: Department of Defense Directive 8320.03, Unique Identification (UID)

Standards for a Net-Centric Department of Defense, March 2007)

Delivery: Applies to the hand-off, which may be physical or virtual in the case of data,

at initial delivery of an item during development, for collaboration, in support of reviews, at

the time of acceptance, and for subsequent modifications, maintenance, refurbishment, or any

other activity that produces new data.

Digital Data: The level of abstraction from which digital (electronically defined)

information and knowledge are derived. A collection of recorded facts, numbers, or datum of a

digitized object that can be defined, annotated, characterized with non-graphical properties and

definition, communicated, stored, and ultimately processed, using business rules, to form

useful information. Also, information prepared by electronic means and made available to

users by electronic data access, interchange, transfer, or on electronic/magnetic media.

(Source: SAE GEIA-HB-649)

Digital Engineering: Engineering performed in a digital collaborative environment

which integrates stakeholders providing authoritative sources of data and models seamlessly

across organizations and disciplines to support life-cycle activities from concept through

disposal.

Digitization: The conversion of analog information into digital form “or as a verb.”

The act of scanning or converting paper or other descriptive elements into electronic paper

such as drawings into machine-readable PDF documents.

Digitalization: The act of transforming paper-based processes and artifacts into the

digital and connected world. Unlike digitization, digitalization is the actual “process” of the

technologically induced changes within these industries. This process has enabled much of the

phenomena today known as the Internet of Things, Industrial Internet, Industry 4.0, big data,

machine-to-machine communication, block-chain, cryptocurrencies, etc.

Digital Transformation: The total and overall effect of digitalization. Digitization has

enabled the process of digitalization, which resulted in stronger opportunities to transform and

change existing business models, socio-economic structures, legal and policy measures,

organizational patterns, cultural barriers, etc.

End Item: A product to be delivered under contract as an intact unit or to be

assembled, completed, and made ready for use as a unit.

Engineering Release: An action whereby configuration information or an item is

officially made available for its intended use. (Source: SAE EIA-649-2)

Governance Model: The framework—principles and structures—through which the

Agency manages the mission, roles, and responsibilities. (Source: NPD 1000.0, NASA

Governance and Strategic Management Handbook)

Mechatronics: A multidisciplinary field of engineering that includes a combination of

systems engineering, mechanical engineering, electrical engineering, telecommunications

engineering, control engineering, and computer engineering. As technology advances, the

subfields of engineering multiply and adapt. Mechatronics' aim is a design process that unifies

these subfields.

Metadata: Data about data, properties (title, document number, creation date, etc.)

used to identify or define a data item. (Source: SAE EIA-649)

Model: A description or representation of a system, entity, phenomena, or process.

(Source: NASA-STD-7009, Standard for Models and Simulations)

Modeling (verb): The physical activity of creating an abstract or digital object that

represents a system, entity, phenomena, or process. (Source: NASA-STD-7009, Standard for

Models and Simulations)

Model Based: An annotated model and its associated data elements that define a

product, which can be used effectively without a drawing. It describes a technology approach

where rigorous visual modeling principles and techniques form the technical foundation for an

engineering or development process to increase its efficiency and productivity. The model is

the source authority that drives all engineering activities.

Model-Based Engineering Framework: The set of processes that defines and utilizes

associated information used to manage and execute the entire life cycle of product data from

its conception, through design, test, qualification, and manufacturing, to service and disposal

and integrates definition and product development data, processes (elements), tools, and

Model-Based Engineering Framework System: A combination and interoperability

connection of systems utilizing information technology applications, user-defined apps, and

processes that implement the management of digital product and systems data within the

extended enterprise (inclusive of Center to Center and inclusive of suppliers, partners, and

primes) across the product life cycle.

Model-Based Manufacturing (MBM): Defines the desired end target state of the earlier

defined model based definition. Test and validation for compliance (model-based compliance

[MBC]) come into play to ensure manufacturing is executing to the proper and correct

requirements, materials are developed or assembled per the proper specification, and process

steps for formulation are followed and executed properly.

Model-Based Systems Engineering (MBSE): The formalized application of modeling

to support system requirements, design, definition, analysis, verification, and validation

activities beginning in the conceptual design phase and continuing throughout development

and later life-cycle phases. (Source: International Council on Systems Engineering (INCOSE),

Systems Engineering Vision 2020, Version 2.03, TP-2004-004-02, September 2007)

Models-Based Approach: An approach to developmental engineering in which the

design and its associated analyses, specifications, etc., are created, used, and managed as a

non-document digital data object (or multiple linked objects); different formats exist to support

different engineering domains, and these divergent needs and data differences impact

interoperability, data integrity, and engineering data management.

Model-Driven Software Engineering (MDSE): A software development methodology

that focuses on creating and exploiting domain models, which are conceptual models of all the

topics related to a specific problem. Hence, it highlights and aims abstract representations of

the knowledge and activities that govern a particular application domain, rather than the

computing (i.e. algorithmic) concepts.

Product: A part of a system consisting of end products that perform operational

functions and enabling products that perform life-cycle services related to the end product or a

result of the technical efforts in the form of a work product (e.g. plan, baseline, or test result).

(Source: NPR 7123.1) Also, the following:

a. Hardware, e.g. engine mechanical part.

b. Software, e.g. computer program or model.

Product Breakdown Structure: A hierarchical view of the relationship of products and

component products. (Source: NPD 7120.4, NASA Engineering and Program/Project

Management Policy)

Product Data and Life-Cycle Management (PDLM): NASA’s strategic business

approach that consists of both PDM (product data management) and PLM (product life-cycle

management). PDLM applies not only to a mechanism to store and retrieve data but also to

manage the data over the product development life cycle. PDLM leverages a consistent set of

business solutions in support of the collaborative creation, management, dissemination, and

use of product definition data/information across the extended enterprise from concept to end

of life.

Product Data Management (PDM): The framework that enables organizations to

manage and control engineering and technical information, specifically data surrounding the

product's design, definition, and related engineering, manufacturing, and logistics processes

and is a key element of PLM. Note: From the product perspective, PDM organizes data

required for design evolution, tracks versions and configurations of evolving design concepts,

and manages archived data and other product-specific information. PDM tools provide access

to product structures and other engineering data such as requirements, as-built data, and

safety and mission assurance data. From the process perspective, PDM systems offer the

capability to orchestrate controlled procedural events such as design reviews, approvals,

product releases, and configuration audits. (Source: NPD 7120.4)

Product Definition Data (PDD): Data that defines the product’s requirements,

documents the product attributes, and is the authoritative source for configuration management

of the product. (Source: Adapted from SAE EIA-649)

Product Life Cycle: A series of states that generally defines the maturity level of a

product and correlates with specific uses or users. Commonly, each state is represented by an

agreed-to collection of information that identifies and establishes the attributes of a product at

a point in time and that serves as the basis for defining change. Note: A product's life cycle

begins with a concept and ends with disposal.

Product Life-Cycle Management (PLM): A strategic business approach that applies a

consistent set of business solutions in support of the collaborative creation, management,

dissemination, and use of product definition data/information across the extended enterprise

from concept to end of life. Note: PLM integrates people/organizations, processes, and

information. In product-dominated endeavors, PLM serves as the information backbone that

extends outside the enterprise. PLM implementations may be composed of multiple elements,

including foundation technologies and standards (e.g. Extensible Markup Language (XML)),

visualization, collaboration, and enterprise application integration), information authoring

tools (e.g. mechanical computer-aided design, electrical computer-aided design, and technical

APPENDIX I

RATIONALE AND INTRODUCTION TO THE DIGITAL

ENGINEERING ENVIRONMENT

I.1 RATIONALE

The creation, usage, and management of digital product-related data used in cradle-to-grave life

cycles are daily events at NASA. The scale and complexity of the data now required for model

and program definition continues to grow not only for product definition but also with regard to

the communication of “smart and intelligent” digital data to and from all program participants.

NASA programs and projects are beginning to use the digital models as the authoritative

understanding of the system, avoiding expensive testing which is no longer a single site activity

but now meaning collaborative work.

In light of the current climate of change, whereas NASA prime contractors and partners are

taking a more active role as “System Integrators,” NASA has identified the need to alter the

current acquisition process to that as a model-based acquisition process—Center-to-Center and

Center-to-commercial supplier product development, collaboration, and interoperability

processes to remain relevant by leveraging model-based techniques, benefits, and collaborative

technologies. Many current revisions of NASA’s Technical Handbooks, although full of sound

engineering principles, do not address today’s digital environment or address MBE practices.

It is incumbent on NASA to develop and adopt new agile approaches achieving greater

performance and affordability to meet the Agency’s current and future challenges. Without

sustained efforts funded with predictable investment to restore agile effectiveness and

modernization, we will rapidly lose our technological advantages, resulting in an organization

that has legacy methods and systems irrelevant to the challenges confronting us. To meet the

Agency’s goals and objectives, we must modernize our thinking and practices to develop

systems and processes that prioritize the speed of development and delivery enabling our

success.

The integration of the information in these models is a challenge, and the size of the data sets

produced by some engineering models strains the limits of some data management and data

transfer systems. New programs need to consider digital elements, including the authoritative

data source repository, shared access, and storage and retrieval mechanisms not only internal to

NASA but also to primes/partners to respond in meeting these challenges. Therefore, the need to

address the acquisition framework must be updated to reflect the model-based environment that

depicts NASA.

I.2 INTRODUCTION

NASA must promote our use of various digital representations of systems and components and

the use of digital artifacts as a technical means of communication across the diverse set of

stakeholders. The MBE strategy addresses a range of disciplines involved with the acquisition

and procurement of systems; and it encourages innovation in the way we design, build, test,

deploy, operate, maintain, and sustain our systems and how we train and shape our workforces to

use these practices.

The way that we do this is by incorporating the use of digital computing, analytical capabilities,

and new technologies to conduct engineering in more integrated virtual environments increasing

customer and vendor engagement, improving collaboration response timelines, fostering

technology infusion, reducing documentation cost, and positively affecting operational and

sustainment affordability. These comprehensive engineering environments will enable NASA

internally and with its industry partners to evolve designs at the conceptual phase, reducing the

need for expensive physical mock-ups, premature design freezing, and physical development

testing.

This NASA Technical Handbook describes the digital engineering vision to modernize how the

Agency designs, develops, delivers, operates, and sustains systems. NASA defines digital

engineering as an integrated digital approach that uses authoritative sources of system data and

models as a continuum across organizations and disciplines to support life-cycle activities from

concept through disposal and the beginnings of the "what" that are necessary to foster the use of

digital engineering practices. This NASA Technical Handbook intends to lay out the foundation

for those implementing the practices who must further develop their "how"—the implementation

steps necessary to apply digital engineering in each of their enterprises and specific

programs/projects. The Centers and programs/projects should develop corresponding digital

engineering implementation plans to ensure the Agency advances this timely and imperative

effort. OCE will develop new and/or update existing Agency policies that support realization of

digital engineering goals (e.g. data rights, intellectual property), develop standard contract

language for RFPs that encourages model-centric interaction between industry and government,

and support standards development to support digital engineering goals.

While this NASA Technical Handbook may not cover all aspects and topics of MBE, references

are provided to the appropriate sources for deeper study and information.

This NASA Technical Handbook addresses:

• A high-level overview of MBE that serves as the core domain and environment from

which subsequent model-based activities (such as manufacturing, acquisition, etc.) will

be based upon.

MODEL-BASED ENGINEERING (MBE) PLAN

J.1 PURPOSE

The purpose of an MBE Plan is to document agreement among the program manager and various

providers of MBE services on how the identified MBE capabilities will be provided. For single-

project or tightly coupled programs (as defined in NPR 7120.5), a single program-wide Plan

should be produced. A variety of program and project documents, project data, and process

requirements will need to be synchronized with this Plan and with the provision of IT-related

capabilities, services, and infrastructure.

J.3 MBE PLAN DEVELOPMENT

MBE Plans reflect the requirements for specific MBE capabilities to support the specific

program/project’s scope, document the choices among alternative delivery mechanisms and

providers, and discuss in detail reliance on IT infrastructure and services. An MBE Plan defines

the scope of each Center's responsibilities, the implementation approach, the environment in

which the program and its projects' MBE solution(s) operates, and timing for implementation of

the MBE solution and associated processes, data, elements, attributes, and formats. The content

of an MBE Plan is affected by both the program/project’s phasing and by current and planned

changes to the IT used to implement MBE (e.g. updates and capabilities committed to by MBE

tool providers). The Plan should be treated as a formally controlled program document.

Concurrence with the Plan is noted by signatures by the program manager, the Mission

Directorate Associate Administrator, and providers of MBE capabilities such as Center Directors

and the Mission Directorates. Project managers for tightly coupled programs are required to sign

the Plan. The Center Directors' concurrence with an MBE Plan documents their commitment to

provide required Center resources to support the program/project as articulated in the MBE Plan.

The Plan needs to be updated annually or at a major KDP. In the case of product life cycle, the

Plan needs to be updated through KDP F (close out/archival of data). At KDP C, the

programs/projects are beginning to understand the data roadmap (Architecture) and inter-

dependencies between the suppliers and NASA.

Elements of a Plan are described as follows:

a. Title page—Document number, document title, release state, and release date.

b. Revision and history—Revision level, change number, description, and release

date.

c. Signature page.

reconciliation of issues emerging from use of

common hardware CAD files and integration of

CAD files across Centers, program elements,

contractors, and partners. Define policies for

identifying the handling of models, simulations,

CAD design documents that are proprietary,

intellectual property, or designated as sensitive but

unclassified (SBU). Identify the program/project data

or documents that the CAD producer is to provide in

addition to the CAD object to assure full PDD such

as parts lists, materials specifications, or acceptance

testing specifications and where such material will be

maintained.

Specialized Libraries and Part Data

MBE Process Lead

Determines what types of libraries and part

objects are required to support the

program/project. Defines the part and

document identification schema.

Describe how elements of the MBE solution will be

used to avoid or reduce the occurrence of duplicate

or multiple part numbers and designations for an

identical physical part. Describe how the

program/project will work with the organizations

responsible for shared part definition libraries,

common model and simulation libraries, and CAD

libraries (whether internal or external to the program)

to ensure approved practices are followed for such

matters as use, naming, and substitutes/alternatives.

Engineering Release, Configuration

Management, and Change Control

Processes

MBE Process Lead

Works with CM organization to define

change control process. Defines and

documents as part of the MBE Plan what

product data is released, when that product

data is to be released, the events that

necessitate product data change, and the

processes that provide the visibility of the

product data configuration life cycle for

internally and externally produced product

data.

Identify existing (or describe the requirements for

modifications to) engineering release and delivery-

of-items processes to support program/project needs

and interoperability across Centers, program

elements, contractors, and partners. Include the

identified solutions (or requested modifications) to

provide visibility of the life cycle, maturity, and

change status of PDD (such as 3D CAD models) and

other engineering models across the program/project

life cycle. Identify the program/project-specific

documents that address engineering release, change

control, and configuration management and

summarize their content, including contractor

configuration management, as required by SAE EIA-

649-2, NASA Configuration Management

Requirements for NASA Enterprises.

Responsibility/Competency

Action

Identify the program/project-specific documents that

address product-related data management with

particular attention to PDD and summarize their

content. Define reports, analyses, data sets, models,

simulations, and documents (especially those leading

up to a design, e.g. stress analyses, thermal, loads,

dynamics) that will be generated for program

management, troubleshooting, and problem

resolution. Define a set of authoritative requirements

and data that represent the various stages of the

products (e.g. as designed, as built, as delivered, as

maintained) that will represent the architecture of the

product at all stages. Describe PDD data delivery

sources, processes, usage, and access rights,

including contractor-originated data across the entire

project life cycle. Identify the source and summarize

relevant content from the program's records plans as

required by NPD 1440.6, NASA Records

Management, and NPR 1441.1, NASA Records

Retention Schedules, and include contractor records

content or identify source documents and their

locations.
