A
2020-06-10
The 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.
B
TBD
Brings into alignment with the update to NPR 7150.2D. Update the Appendix A table containing the additional areas to consider when identifying software causes in Hazard Analysis.
Forward

1. Confirm that the project collects, tracks, and reports on the software volatility metrics. 2. Analyze software volatility metrics to evaluate requirements stability as an early indicator of project problems.
The project manager shall track and maintain software non-conformances (including defects in tools and appropriate ground software).
1. Confirm that all software non-conformances are recorded and tracked to resolution.2. Confirm that accepted non-conformances include the rationale for the non-conformance.
The project manager shall define and implement clear software severity levels for all software non-conformances (including tools, COTS, GOTS, MOTS, OSS, reused software components, and applicable ground systems).
1. Confirm that all software non-conformances severity levels are defined. 2. Assess the application and accuracy of the defined severity levels to software non-conformances.3. Confirm that the project assigns severity levels to non-conformances associated with tools, COTS, GOTS, MOTS, OSS, and reused software components. 4. Maintain or access the number of software non-conformances at each severity level for each software configuration item.

The project manager shall implement process assessments for all high severity software non-conformances (closed loop process).
1. Perform or confirm that a root cause analysis has been completed on all identified high severity software non-conformances, and that the results are recorded and have been assessed for adequacy. 2. Confirm that the project analyzed the processes identified in the root cause analysis associated with the high severity software non-conformances. 3. Assess opportunities for improvement on the processes identified in the root cause analysis associated with the high severity software non-conformances. 4. Perform or confirm tracking of corrective actions to closure on high severity software non-conformances.

3. Example of Table from Software Assurance Plan
Note
The table below was taken from excerpts from Software Assurance Plan in SWEHBVD. The table is built from SWE excerpts plus SA Tasks using the individual SA tasks from the "SA Tasks from NASA-STD-8739.8B" area of SITE.
The advantage of using this technique is that changes to the requirements (from SWEHBVD SWEs) and SA Tasks (from NASA-STD-8739.8B) will be made in one place. Once the updates are made, all of the places where they are repeated (quoted) are automatically updated.
It is a little one time work to setup. It saves time as updates are made in documents.
