...

• Implementation and Unit Testing - Implements the Design into one or more code modules. 
• Preliminary Design Review
• Critical Design Review
• Test Readiness Review
• Operational Readiness Review

1.5 Activity Repetition

• Design is always done once. It should be peer reviewed and analyzed by Software Assurance. 
• Design may be reviewed and re-analyzed as often as there are significant changes in architecture or requirements. For example:  
  • Technology changes to the architecture requires changes to the design
  • Customer changes to requirements require changes to the design

3. Software Assurance Software Assurance is integral to the performance of all Software Development activities. It includes Process Monitoring as well as Process Analysis.  Process Monitoring - addresses the question, "Is the development team following their processes and producing the expected work products?" Process Analysis - addresses the question, "Are there better ways of performing the processes that would result in the early discovery of defects?" 3.1 Software Assurance Tasks from SWEs Software Assurance Tasks are included in tab 7 of the SWEs.  SWE-058 - Detailed Design with new tab 4 Expand title SWE-058 SA Tasking and Work Product Details Link to SWE-058 - Copy of SWE-058 - Detailed Design with new tab 4 SWE-058 Requirement Excerpt Include Copy of SWE-058 - Detailed Design with new tab 4 Copy of SWE-058 - Detailed Design with new tab 4 nopanel true Tasking From NASA-STD-8739.8B Include Page SWE-058 - SA Task1 SWE-058 - SA Task1 Include Page SWE-058 - SA Task2 SWE-058 - SA Task2 Include Page SWE-058 - SA Task3 SWE-058 - SA Task3 Include Page SWE-058 - SA Task4 SWE-058 - SA Task4 Include Page SWE-058 - SA Task5 SWE-058 - SA Task5 SA Work Products Include Page SWE-058-SAWP SWE-058-SAWP 3.2 Topics and Other Supporting Materials 3.2.1 Topics Topic 8.16 - 8.55 - Software Design Analysis Excerpt Include SWEHBVD:8.55 - Software Design Analysis SWEHBVD:8.55 - Software Design Analysis nopanel true Expand title SA Tasking from Topic 8.16 - Software Design Analysis SWE-034 - Acceptance Criteria Include Page SWE-034 - SA Task1 SWE-034 - SA Task1 SWE-134 - Safety-Critical Software Design Requirements Include Page SWE-134 - SA Task1 SWE-134 - SA Task1 Include Page SWE-134 - SA Task4 SWE-134 - SA Task4 Include Page SWE-134 - SA Task5 SWE-134 - SA Task5 Include Page SWE-134 - SA Task6 SWE-134 - SA Task6 SWE-057 - Software Architecture Include Page SWE-057 - SA Task1 SWE-057 - SA Task1 Include Page SWE-057 - SA Task2 SWE-057 - SA Task2 SWE-143 - Software Architecture Review Include Page SWE-143 - SA Task1 SWE-143 - SA Task1 SWE-080 - Track and Evaluate Changes Include Page SWE-080 - SA Task1 SWE-080 - SA Task1 SWE-081 - Identify Software CM Items Include Page SWE-081 - SA Task2 SWE-081 - SA Task2 SWE-203 - Mandatory Assessments for Non-Conformances Include Page SWE-203 - SA Task2 SWE-203 - SA Task2 3.2.2 Process Asset Templates Include Page Design Analysis Assets Process Asset Templates Design Analysis Assets Process Asset Templates 3.3 Other Associated SWEs, Topics, etc.
