An IATF 16949 audit checklist is a comprehensive list that quality managers use to evaluate if the company’s QMS is aligned to the IATF 16949:2016 standard. As IATF 16949 is applicable to automotive suppliers, the primary objective of the IATF 16949 audit checklist is to ensure that the QMS promotes defect prevention, continuous quality improvement, and waste reduction in the supply chain.
