Is anybody aware of a requirement that the problem-solving method of a supplier be documented? I'm hearing from my registrar that the IAOB requires it but the IAOB website says nothing.
I can't recall seeing a specific requirement that the problem-solving method be documented, but recall that there's a general expectation that important processes should be documented, where the availability of a documented process/procedure would prevent nonconformities.
220.127.116.11 Problem solving The organization shall have a defined process for problem solving leading to root cause identification and
If a customer-prescribed problem-solving format exists, the organization shall use the prescribed format.
