My $.02 worth.
I've had at least 3 PPAPs rejected because there was no mention of verifying the incoming materials were within specification (whether a Purchasing spec - raw mat'l - or a component spec) in the
PFMEA or CP. I also used to get caught up in "Where does it say I have to?". As I thought about it, we actually do perform receiving inspection and it actually is part of our process flow and we actually do have procedures for receiving inspection - so why wouldn't it be included in our process flow. All of a sudden my customers' demands made sense and receiving inspection has been a step in our process flow since.
Whether it is a "Product audit", Process audit", or any other kind of "audit", it's not part of our flow because of a "
Shall , "
Should ", or "
Could . It's part of our flow because
it makes sense for us.
Sorry for the mini-rambling (had to go through this very exersize with our MR today. She wanted the inspection steps (among some others) pulled out so they couldn't be audited

). Hope I haven't gotten too far off topic but I'm plenty tired of not using common sense because of the absence of a "
shall " in some standard.
I better go tip a few. Have a great weekend all
