Re: Who should prepare DVP for components, our suppliers or our product engineering?
I think whoever is design responsible for the component should be responsible for the DVP. Even if your supplier is design responsible, you should still review and approve their DVP, and probably you should have some expectations/assumptions as to what would be included in the DVP.
(Ultimetly if there is a failure at YOUR customer, they are going to come to you, not your supplier, so it is ultimetly YOUR responsibility to ensure everything is designed proerly.)
