"Refer to Checklist ISO/TS 16949: 2002, IATF expects auditor to audit "Customer Owned Processes (COP)."
1- I may hve overlooked the term, specifically what page or paragraph is located on/in?
"It means beyond defining organization's QMS process needed. Does the organization need to define the COP or do something else to prepare for COP auditing?"
2- the method of definng customer oriented processes (COP's) is used ONLY as a guide in understanding and auditing the process approach. It is NOT a requirement to have a list of COP's. The requirement is to define the process,as you see it, to meet the customer requirements.
Caveat; However, some registrars are requireing that you use this approach. If you select a registrar that does, then it will become a requirement.
"and What's really COP definition?"
3- is defined as; the direct inputs from the customer to the organization and the resultant direct outputs from the organization to the customer.
