My business has been ISO9001 certified for many years and has a growth opportunity that requires IATF16949 accreditation. The opportunity is small yet impactful so I am looking to see if I can become certified for just one part number. Our current registrar has not been entirely convincing that this is possible. IATF16949 accreditation is not in our strategic plan and I do not want to rewrite our QMS and would rather bolt on the necessary processes that would cover only this one part. Has anyone been successful in accomplishing this feat without too much disruption to their existing QMS?
