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.

titleInputs, Outputs, and Predecessor Activities

Activity graphical representation of Inputs, Outputs, Predecessor and Successor Activities as appropriate. Not meant to be exhaustive, but representative of a typical project. 


1.1 Inputs

Note

List of some of the inputs from other activities that are necessary for the activity to begin. 

Examples: 

1.2 Predecessor Activities

Note

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

Examples: 

1.3 Outputs

Note

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. 

Output Work ProductUsed by Downstream Activity


1.4 Successor Activities

Note

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

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
  • ACTIVITY is always done once. Ideally it will be peer reviewed and analyzed by Software Assurance. 
  • ACTIVITY 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 ACTIVITY
    • Customer changes to requirements require changes to the ACTIVITY

1.6 Center Resources From SPAN

Note

Add links to SPAN activity pages that are appropriate for this activity. Use links from the Activity section of the front page. SPAN

Several Centers Process Asset Libraries have materials related to this activity. Related Processes, templates, and other resources may be found in the following Activities in SPAN (available to NASA only).

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.
