I've got your point, enjoyed this discussion, learned quite a bit, and have modified my stark views (to a degree), but will examine further.You also cannot write up as a non-conformance, something you cannot observe.
If procedures are accurate, being followed and the output is good...
If everyone you talk to seems to have a good grasp of the system and how it works....If rejections, returns, rework etc is under control....If you are told by multiple people that "We request a change - Joe makes the change - we check it - and Joe issues it....
It can hardly matter that you can't "Audit past approvals". What you have discovered, and have evidence of, is that the "system" is in place, understood, functioning properly and effective...
If on the other hand you discover the opposite of the above, if you discover outdated documents, poor understanding, conflicting answers etc, then you have evidence to question the process....Whether you can see documented "past approvals" or not.
I think that the bottom line is that, and effective system can and does work well without a lot of "sign-offs" while a poor and/or ineffective system will still be ineffective with a whole "drawer full" of sign-offs.
