Harry,
I may be getting things wrong here, but...
Within my quality system manual e.g. under Procedure 04 Document Control 4.2.3 it has 2/3 paragrpahs which define where the master copies are stored, who has access, who issues documents, how drawings are marked/superseded etc etc.
Is this not sufficient without writing a separate procedure. Maybe my manual is in the wrong format but never had any issues previously.
This is possibly why my manual seems a bit long winded. Its roughly 40 pages long. Bear in mind I ain't no Quality Manager officially, just an engineer who is trying to develop a better system.!
