NCR and CAR

NCR = Non-Conformance Report
CAR = Corrective Action Request

NCR is a report that provides details of non-conformity encounters.

CAR is report that requests to review non-conformity and take action to eliminate the causes of nonconformity.

The observer (generally an auditor) of non-conformance raises a NCR (non-conformance report) and ask for a CAR (corrective action request) to the person responsible for the NC (non-conformance). The corrective action initiated can be part of NCR/CAR.
