1.4 Successor Activities

NoteLinks to Activities which might be started or supported by this activity. 

• 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

note

Describe what conditions determine if the activity needs to be repeated, such as re-planning after a change in requirements or schedule constraints. 

• How much of the activity needs to be repeated
• Frequency of 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 Activity 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 in this activity.  3.1.1 .  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 Software Assurance SA Work Products  Software Design Analysis  Results of software assurance design analysis, including assessments in Tasks 1, 2, and 3.   List of any identified design risks and issues.
