List of some of the other activities that must be started (not necessarily completed) so that this activity may begin. 

Examples: 

Predecessor Activities are performed before Design. These activities produce the work products that will be reviewed. 

1.3 Outputs

List of some of the outputs or work products of the activity. These are typically used as inputs by the downstream activity. In some cases there is a supporting SWE associated with the work product.

1. Introduction

Note

Typically starts with a quote from the NPR that helps define the activity. Additional descriptive material is meant to help define the activity but not be so detailed that it pulls in all of the guidance from the SWEs in the activity.

Software peer reviews and inspections are the in-process technical examination of work products by peers to find and eliminate defects early in the life cycle. Software peer reviews and inspections are performed following defined procedures covering the preparation for the review, the review itself is conducted, results are recorded, results are reported, and completion criteria is certified. When planning the composition of a software peer review or inspection team, consider including software testing, system testing, software assurance, software safety, software cybersecurity, and software IV&V personnel.

1.4 Successor Activities

Note
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

1.6 Center Resources From SPAN

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.
