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.

BTBDBrings 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.

3. Example of Table from Software Assurance Plan

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.
