Bringing back to life this thread, I'm new in the automotive industry and I'm working with PPAPs so I'm trying to learn as much as possible... But related to this comment by Jim, do you recommend if we purchase a product that then is sold to our customer, to include the PSW we signed to our supplier in the PPAP we are submitting to our customer as a way of "saying" that we "approved" the part they're selling us and that they meet all of our requirements (that includes our customer requirements)? I'm not sure if that is ok or if this documentation (PPAP from supplier) should be treated as "confidential".... what are your thoughts?
