Hi MonteS,
I agree with Ronen. As a component manufacturer you are not subject to ISO 13485, but your client is and its easier for them to expect more of you weather justified or not. I doubt anyone will challenge them about your IQ/OQ processes unless there is a serious investigation going on.
Anyhow, the client is the client and you need to be smart in producing retrospective report (you can do IQ and OQ together) that shows that your process consistently produces good results.
