Appendix C. Requirements Mapping and Compliance Matrix

C.1 The rationale for the requirements is contained in the NASA Software Engineering Handbook, NASA-HDB-2203. Programs/Projects may substitute a matrix that documents their compliance with their particular Center's implementation of NPR 7150.2, if applicable. See NASA-HDBK-2203 for compliance matrices organized by class and safety-criticality, tailoring field for each requirement, tailoring rationale, and approval signature lines.

C.2 The Compliance Matrix documents the program/project's compliance or intent to comply with the requirements of this NPR or justification for tailoring. The matrix lists:

a. The unique requirement identifier.

b. The section reference.

c. The NPR 7150.2 requirement statement.

d. The Technical Authority Level responsible for assessing a project's compliance matrices, tailoring, waivers, and deviations from requirements in this NPR.

e. The requirement owner (the organization or individual responsible for the requirement).

f. The applicability of the requirements in this NPR to specific systems and subsystems within the Agency's investment areas, programs, and projects is determined through the use of the NASA-wide definition of software classes.

C.3 Tailoring Guidance

X - Indicates an invoked requirement by this NPR consistent with Software Classification (ref. SWE-139). May be tailored with Technical Authority approval (ref. Chapter 2.2).

Blank - Optional/Not invoked by this NPR.

X (not OTS) - Does not apply to Off the Shelf (OTS), Commercial Software.

Center Director - Center Director or the Center Director's designated Engineering Technical Authority or Center Director's designated Safety and Mission Assurance Technical Authority.

Note 1 - Project is required to meet this requirement to the extent necessary to satisfy safety critical aspects of the software. All Safety-critical software has to be classified as Class D or Higher.

Note 2 - Applies to Class B software except for Class B software on NASA Class D payloads, as defined in NPR 8705.4. For Class B software, in lieu of a CMMI rating by a development organization, the project will conduct an evaluation, performed by a qualified evaluator selected by the Center Engineering Technical Authority, of the seven process areas listed in SWE-032 and mitigate any risk, if deficient. This exception is intended to be used in those cases in which NASA wishes to purchase a product from the "best of class provider," but the best of class provider does not have the required CMMI rating. When this exception is exercised, the Center Engineering Technical Authority should be notified.

Note 3 - For tailoring of NASA-STD-8739.8 and NASA-STD-8719.13, the Software Assurance Standard and the Software Safety Standard respectively, use the tailoring provided within those documents. They are both risk based and Software Class based tailoring.

Note 4 - The Technical Authority implementation responsibilities for Class F software is at the NASA Headquarters Chief Information Officer (CIO) level, the Technical Authority implementation responsibilities for Class G and H is at the Center CIO organization level or at the level defined in the Center Technical Authority implementation plan. All Safety-critical software has to be classified as Class D or higher.
