As a Tier 2 supplier of automotive stampings, we have our IATF 16949 certification. A finding from our latest audit, determined we need to better document how we are confirming our CSR's. (Better will be easy since we are not currently documenting it at all.) After combing through our customer's supplier quality manual and supplier portal requirements, I have not found where any OEM CSR's are passed down to us. I plan to put a blurb in our quality manual that states that any revision to our customer's quality manual would trigger a review to search for any CSR's that are potentially passed on as a part of the revision. So for our record I only plan to do a matrix to document the review of each new release of our customers supplier quality manual for any added OEM CSR's. Other than that, the only thing left would be the MAQMSR for us to adhere to. Since we are IATF1649, I believe we should be able to ignore those requirements since they would be automatically accounted for as a part of the IATF requirements. Can someone confirm my understanding of this requirement is correct and if the IATF requirement would be met using my planned documentation method? Thanks in advance for your assistance.
