Hi Scott,
Yes, customer is a medical device company. We make a small component for them.
I'm only 6 months in this position and the validation process on the machine was carried out 3 years ago. We had to replace the existing machine as replacement parts had become obsolete for it and we couldn't stand over it's reliability anymore.
The acceptance criteria and results are stated so I don't see how this non-conformance stands. The "original" hand written results from the validation exercise were not kept but there is a typed out version of them held on file. (This should be against 7.5.3.2 of ISO 9001 in my opinion).
Our validation procedure is a little vague, but it kind of needs to be as we need to be flexible from one customer to the next
