7.5, 7.6 - Traceability of 7150.2 to other NPRs, NASA-STDs
Unknown macro: {div3}

1 - Purpose

This information is intended to enhance project teams' understanding of the relationship between NPR 7150.2 requirements and other NASA software requirements. 

For instance, software assurance activities require input, such as documents or process records, from projects.  When project personnel understand the relationship of the software assurance requirements to the software engineering requirements, the requests from software assurance personnel are more likely to seem reasonable and the results software assurance personnel produce may be more acceptable to the project.

Unknown macro: {div3}

2 - Traceability to Other NASA Procedural Requirements (NPRs)

This spreadsheet identifies relationships between the requirements ("shall" statements) in NPR 7150.2 for Software Engineering, and the parent policy NPD 7120.4D3 addressing Engineering and Program/Project Management, NPR 7123.1A1 addressing Systems Engineering, and NPR 7120.52 (NM 7120-18) addressing Program and Project Management.

Draft versions of this spreadsheet were reviewed by the NPR 7150.2 guidance handbook team as well as OCE representatives before being approved for use by the NASA community.

Because this spreadsheet was generated as a guidance tool for NPR 7150.2, the NPR 7150.2 requirements are listed in the chart along with their identifiers (SWE numbers). All requirements mapped to the NPR 7150.2 requirements are identified by the clause number in their respective document. Empty cells indicate no related requirement in that particular document. Clarifying phrases and references to appendices where explanatory details are found are noted throughout the spreadsheet.

2.1 NPRs Mapping Spreadsheet

The following spreadsheet is available for download from the web. Download here: [^NPR 7150 traced to NPR 7123 and NPR 7120_20100716_V2.xlsx]

This spreadsheet has multiple columns, as described below:

  • Column A: 7120.4D Section # - This column lists each section of NPR 7120.4D and indicates which have mappings to NPR 7150.2.
  • Column B/C: 7150 requirement & SWE-Number - These columns show the text of each of the NPR 7150.2 requirements (Column B) with the SWE requirement numbers (Column C)
  • Column D: 7123.1A Section # - This column lists each section of NPR 7123.1A and indicates which have mappings to NPR 7150.2.
  • Column E: 7120.5D Section # - This column lists each section of NPR 7120.5D and indicates which have mappings to NPR 7150.2.

3 - Traceability to Other NASA Standards (STDs)

This spreadsheet identifies relationships between the requirements ("shall" statements) in NPR 7150.2 for Software Engineering, and the engineering standards of NASA-STD-8739.84 addressing Software Assurance and NASA-STD-8719.13B5 addressing Software Safety.

Because this spreadsheet was generated as a guidance tool for NPR 7150.2, the NPR 7150.2 requirements are listed in the chart along with their identifiers (SWE numbers). All requirements mapped to the NPR 7150.2 requirements are identified by the clause number in their respective document. Empty cells indicate no related requirement in that particular document. Clarifying phrases and references to appendices where explanatory details are found are noted throughout the spreadsheet.

3.1 STDs Mapping Spreadsheet

The following spreadsheet is available for download from the web. Download here: [^NPR 7150 traced to NASA-STD-8739 8 and NASA-STD-8719 13B_20100924.xls]

This spreadsheet has multiple columns, as described below:

  • Column A: 7150 requirement & SWE-Number - These columns show the text of each of the NPR 7150.2 requirements with the SWE requirement numbers
  • Column B: NASA-STD-8739.8 Section # - This column lists each section of NASA-STD-8739.8 and indicates which have mappings to NPR 7150.2.
  • Column C: NASA-STD-8719.13B Section # - This column lists each section of NASA-STD-8719.13B and indicates which have mappings to NPR 7150.2.
Unknown macro: {div3}
