Software Engineering

16.2.1 
Record engineering change requests and proposals
Every change request or proposal should be recorded in a change-tracking logbook 
or repository. This record of requested modifications to the software architecture 
provides a measurement of the stability of the software architecture.
The number of changes registered against each partition of the architecture 
should become more infrequent as the architecture evolves and matures. Ideally, the 
number of modifications requested against a partition of the architecture will cease 
prior to the technical review where the partition is to be presented.
An engineering change record should include the following information to per-
mit tracking and status reporting:
●
  Change request or proposal number
●
  Date initiated
●
  Organization that initiated the change
●
  Class of change
●
 Priority
●
  Primary architecture partition impacted (requirements baseline, functional or 
physical architectures)
●
 Disposition
●
  Disposition date
●
  Assimilation status
