Operator observance audit

I am not sure I understood your question entirely. However, there is no direct operator observance audit issue in the IATF 16949 standard.

But what I understand is, the issue of layer audit, which is the customer-specific requirement of FORD and GM. Operator behaviors are routinely monitored during layer audits.

Layer audit is also the subject of a manufacturing process audit, and the IATF 16949 standard number is 9.2.2.3 under internal audit requirement.
