Responsible Office: Office of Safety and Mission Assurance

Appendix E. Assurance Implementation Matrix (AIM)

E.1 This Assurance Implementation Matrix is used by projects to:

a. Facilitate early discussions between the MDAA, Program/Project, and the TAs to reach agreement upfront around high-level SMA objectives, expected results, and corresponding approaches to meet those objectives commensurate with the established risk class(es).

b. Document their planned implementation consistent with the established risk class(es) and SMA objectives in Appendix D to inform more detailed SMA planning and implementation.

E.2 Mission Directorates may choose to invoke a MAR document on a program or project that serves as the baseline set of mission assurance requirements. If the OSMA has concurred with the Mission Directorate’s determination to invoke their MAR on a program or project, programs or projects achieve compliance with the invoked Mission Directorate MAR (e.g., SPD-39) in lieu of establishing an Assurance Implementation Matrix.

E.3 Instructions for completing each column of the AIM are as follows:

a. NPR 8705.4, Risk Tolerance Class Objectives and Approved Standards: Include the objectives and accepted standards provided in Appendix D corresponding with the risk tolerance class designated to associated mission or instrument.

b. Objective Satisfied (Y/N): Provide a “Yes” or “No” answer to whether the project plans to satisfy the corresponding objective provided.

c. Project Implementation: Document the project-specific implementation to satisfy the corresponding objective provided, including any approaches provided in the associated NASA-accepted standard(s).

d. Alternate Approaches and Standards: Include details for any alternate approaches or standards proposed and the related project-specific implementation to satisfy the corresponding objective provided.
