Design authority

Incomplete capability

  • No description of who have design authority exists.

  • Decisions affecting the configuration are taken without a certainty that a delegated design authority exists.

  • Understanding the meaning of design authority.

  • Understand the concept of CCB

Performed capability

  • Design authority is defined to some extent, but with some ambiguities and unclarities.

  • Responsibilities for CCB are unclear and processes and methods for change control are not working effectively.

It is essential that the organisation have established which role in the organisation that have the authority to decide on configuration issues. For complex systems, the authority need to be delegated along the system hierarchy or for specific functions. 

To secure that all relevant aspects of a design decision are covered, a common approach is to assign the authority to a Configuration Control Board (CCB). Typically the responsibilities for a CCB include:

  • The establishment of formal baselines

  • Deciding on change proposals affecting requirements, baselines and engineering design


Managed capability

  • Design authority and how it is delegated is clearly defined

  • If CCB is applied, routines for performing CCBs are well documented and implemented in the organisation. The CCB has a clear mandate and the roles involved is aware of their responsibility and mandate.
