Have any of you guys had to submit 'Interim PPAPs'?
I have a customer, whose end customer is part of the GM conglomerate, that demands an interim PPAP. Which, basically, is a PPAP with some documents missing. We shipped pre-production parts (electronic components) and now have been asked for an interim PPAP consisting of all the documents that we have for a full PPAP plus a timing plan for documents that are not yet ready (R&R studies, Cp&Cpk data, reliability data etc.)plus completion of the "GM-1411 Interim recovery worksheet" (which sadly is not the latest revision on their own website). Is this normal for GM, triplication of paperwork?

I dont think there is anything "normal" about GM's procedures, and the situation you described does not surprise me. My experience w/GM is: The requirements GM places on your company are SQE/A dependant. I know GM suppliers that have been working from "interim" PPAP's for years! It is not uncommon for a SQE/A to accept a PPAP just to have that persons successor reject it.

I've done plenty of interim PPAP's. The interim worksheet should serve as the Timing
Plan. Unless there are so many issues that a separate plan was requested. As for "is this normal for GM, triplication of paperwork? Seems to happen quite often anyways....
