Note: Some paragraphs have changed pages as a result of these changes. Only pages where content has changed are identified by change indications.

A2020-06-10The revised document addresses the following significant issues: combined the NASA Software Assurance Standard (NASA-STD-8739.8) with the NASA Software Safety Standard (NASA-STD-8719.13), reduction of requirements, bring into alignment with updates to NPR 7150.2, added a section on IV&V requirements to perform IV&V, and moved guidance text to an Electronic Handbook. This change combines the updates to NASA-STD-8739.8 and the content of NASA-STD-8719.13. The update includes the NASA software safety requirements and cancels NASA-STD-8719.13 standard.

SOFTWARE ASSURANCE AND SOFTWARE SAFETY STANDARD


1. SCOPE

1.1 Document Purpose

1.1.1     The purpose of the Software Assurance and Software Safety Standard is to define the requirements to implement a systematic approach to Software Assurance (SA), software safety, and Independent Verification and Validation (IV&V) for software created, acquired, provided, or maintained by or for NASA. Various personnel in the program, project, or facility, and Safety and Mission Assurance (SMA) organizations can perform the activities required to satisfy these requirements. The Software Assurance and Software Safety Standard provides a basis for personnel to perform software assurance, software safety, and IV&V activities consistently throughout the life of the software, that is, from its conception, through creation to operations and maintenance, and until the software is retired.
