1. Requirements Mapping and Compliance Matrix

1.1 The Software Classification Spreadsheet

To download the Software Classification Spreadsheet ⁴⁴³, please click the link: Compliance Matrix for Each Class

1.2 Rationale

The rationale for the requirements is contained in this Handbook (NASA Software Engineering Handbook, NASA-HDBK-2203). Programs/Projects may substitute a matrix that documents their compliance with their particular Center's implementation of NPR 7150.2 ⁰⁸³, if applicable. This topic contains a compliance matrix for the requirements organized by class and including a tailoring field for each requirement, tailoring rationale, and approval signature lines.

The Compliance Matrix documents the program/project's compliance or intent to comply with the requirements of NPR 7150.2 ⁰⁸³ or justification for tailoring. The matrix lists:

1. 1. The unique requirement identifier.
   2. The section reference.
   3. The NPR 7150.2 ⁰⁸³ requirement statement.
   4. The Technical Authority Level responsible for assessing a project's compliance matrices, tailoring, waivers, and deviations from requirements in NPR 7150.2.
   5. The applicability of the requirements in NPR 7150.2 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.

1.3 Tailoring Guidance

Use the following guidance, also included in the matrix, to interpret the contents of the compliance matrix included in this topic:

X - Indicates an invoked requirement by this NPR consistent with Software Classification (See SWE-139). May be tailored with Technical Authority approval (NPR 7150.2, Chapter 2.2).

Blank - Optional/Not invoked by NPR 7150.2.

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

Each requirement in this Handbook also includes a graphical representation of its compliance matrix data:
