Just because you got a perfect score does not mean the auditor was bad. Your Internal Auditing system must have been thorough in dissecting your QMS. We also completed our ISO-TS16949 recertification audit-two auditors auditing independently. The size of the plant is big- 300 employees. The CB even went overseas to audit the support process. The result was ZERO nonconformance. The reason is this: we did an excellent job preparing for this recertification audit. It was a thorough and exhaustive audit. I had to relay on this website to answer all my concerns before the audit. IATF had done witness audits on our auditors. I cannot always guarantee that my audits are perfect though I strive to make it happen.
