This was a post about AndyN, and since he is not here anymore, could anyone else clarify me something?
No, it's not about document change control which is looked after elsewhere. The fundamental reason for change control in section 8 is that, once you've defined a process, put in place objectives, controls and measurement/monitoring, things shouldn't be allowed to change in an uncontrolled/unapproved manner. Yes, it does affect documents at some time, but that's incidental.
Wouldn´t the whole process of document control (approval, etc) of Procedures, Work Instructions and if you have, Process Diagrams or Process Descriptions, do exactly that (not allow change in uncontrolled/unapproved manner)?
Why create a new process to control change if it's already implemented in the Document Control processes, and documents describing the process?
