I don't know how it works on the Prod car side of things, but don't be too quick to blame the CRB. Yes, they are the final word and the conduit that you see, but the PAC is the committee that does the legwork and makes the recommendations.

In IT, most of the calls are made by the ITAC. The CRb makes suggestions and comments, and asks questions for better understanding, and prvides background info, but most of the calls are ITAC calls.

So, look up who's on the PAC, and go have a chat if you want to understand how things really happened.
