h3. 1 - Introduction

This information is intended to enhance project teams' understanding of the relationship between NPR 7150.2A 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.

h3. 2 - Traceability to Other NASA Procedural Requirements (NPRs)

Documents in this section:
* [NPR-7123.1A (NASA Systems Engineering Processes and Requirements)|http://nodis3.gsfc.nasa.gov/displayDir.cfm?t=NPR&c=7123&s=1A]
* [NPR-7120.5D (NASA Space Flight Program and Project Management Requirements)|http://nodis3.gsfc.nasa.gov/displayDir.cfm?Internal_ID=N_PR_7120_005D_]
* [NPR-7120.4D (NASA Engineering and Program/Project Management Policy)|http://nodis3.gsfc.nasa.gov/displayDir.cfm?t=NPD&c=7120&s=4D]

This spreadsheet identifies relationships between the requirements ("shall" statements) in NPR 7150.2A for Software Engineering, and the parent policy NPD 7120.4D addressing Engineering and Program/Project Management, NPR 7123.1A addressing Systems Engineering, and NPR 7120.5 (NM 7120-18) addressing Program and Project Management.

Draft versions of this spreadsheet were reviewed by the NPR 7150.2A 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 7150.2A, the NPR 7150.2A requirements are listed in the chart along with their identifiers (SWE numbers).  All requirements mapped to the NPR 7150.2A 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.

The following spreadsheet is available for download from the web. Download here: 

This spreadsheet has multiple columns, as described below:
* *Column A: 7120.4D Section #*
* *Column B/C: 7150 requirement & SWE-Number *\- These columns show the text of each of the NPR 7150.2A requirements (_Column B_) with the SWE requirement numbers (_Column C_)
* *Column D: 7123.1A Section # *\- This table lists each section of NPR 7123.1A and indicates which have mappings to NPR 7150.2A.
* *Column E: 7120.5D Section # *\- This table lists each section of NPR 7120.5D and indicates which have mappings to NPR 7150.2A.
