This is a working page to build the list of activities and the SWEs and topics that define them.
The table below was built from the activity descriptions in NPR 7150.2D chapters 3 thru 5. These are highlighted in yellow.
Additional activities were derived from chapter 2 and are highlighted blue below as the first 7 activities. These chapter 2 activities were then copied into the activities highlighted in yellow where they seemed most likely to belong.
Distribution Of SWEs Into Activities
- All SWEs in NPR 7150.2D are represented in an activity in the yellow group. SWEs that come from chapter 2 represent things that are done at the Institutional level to enable projects to perform a SWE at the project level. In a sense, they are enabling SWEs.
Distribution Of Topics And PATs Into Activities
- All topics are represented in at least one activity.
- Some topics are associated with multiple SWEs and may appear in more than one activity. For example, topic 8.5 - SW Failure Modes and Effects Analysis deals with design as well as has safety related considerations as well. It appears in both the 3.7 Safety-Critical Software and 4.3 Software Design activities.
- All PATs are represented in at least one activity. Some PATs may appear in multiple activities depending on the same criteria as topics.
Topics That Don't Fit Into Activities
- There are a few topics that don't fit into the activity scheme. They are listed in the next to last row in the red highlight.
Activities That Are Not Represented In This Model
- There are a few topics that are not represented in this activity model. They are listed in the last row in the green highlight. If we want this activity model to match more closely with the way projects do their work, it may be necessary to add these activities into the model and move the appropriate SWEs, Topics, PATs, etc. into them.
Additional Considerations Moving Forward
- 3.8 Automatic Generation of Software Source Code content might be better to put into the activity 4.3 Software Design or 4.4 Software Implementation
- 3.12 Software Bi-Directional Traceability has only one SWE and no other topics or other materials associated with it. It may be more appropriate to put this SWE under 4.1 Software Requirements
- 4.2 Software Architecture and 4.3 Software Design might be better to consider as a single activity.
