The intent of third party audits is to provide assurance that a company complies with a standard or specification.
Many people say that third party audits will eliminate customer audits. This has not been the case up to now in part because customers still see the need to ensure compliance to their specific requirements. Even QS-9000 (now IATF 16949) , specific to Ford, GM and Chrysler suppliers, does not eliminate customer audits.
