What is the basic difference between CAR and NCR, explain in terms of ISO 9001:2008?

The observer of Nonconformance  "NC" raises a report called NCR and he asked for a corrective action report "CAR" to the originator of the NC. and if observer of NC will be agree to this CAR , then the corrective action will be implemented

·        CAR: Corrective Action Request: CAR stands for Corrective Action Request, and it means the activity of originating a Corrective Action. In the ISO arena, CAR is by far one of the most frequently used terms for Corrective Action. The essence of CAR is to conduct investigation on a problem which already happened and needs root cause analysis and resolution to prevent recurrence. Although the acronym translates to Corrective Action Request, when companies use this acronym, they actually use it for their entire Corrective Action lifecycle rather than just the request portion.

·        NCR: Non-Conformance Report: NCR seems, to me, one of the most widely misunderstood acronyms. Most people tend to confuse NCR with a Corrective Action or, worse yet, with an Audit Nonconformity. First of all, a Nonconformance is an instance when a product does not meet product specifications — whether the nonconformity is major or minor – and therefore does not conform to requirements (hence the term Nonconformance). Nonconformance Reports, or NCRs, log and track the occurrence of Nonconformance’s either in paperwork or in electronic form.
