DoD Requirements Management provides traceability back to user-defined capabilities documented in the Initial Capabilities Document (ICD), Capability Development Document (CDD), and Capability Production Document (CPD). A good requirements management system should allow for traceability from the lowest level component in the Weapons System Specification (WSS) all the way back to the ICD. Relational databases are a good tool in doing this. The Program Manager (PM) and Chief Systems Engineer should institute a Requirements Management process to do the following:

  • Maintain the traceability of all requirements from capabilities needs through design and test,
  • Document all changes to those requirements, and
  • Record the rationale for those changes
