Hi Iceman,
We have a follow-up or "audit" on each Corrective and Preventative Action item brought up, no matter how minute. It is actually part of the Request for Action (RFA) form we use to log and track CAR's & PAR's. Upon completion of the CAR/PAR, the RFA is logged into the system and I assign a follow-up date. This follow-up date is based upon the nature of the CAR/PAR and is designed to be timely, yet allow enough time for the action to be properly and thoroughly tested. If, during the follow-up, further corrective/preventative action is required, the matter is brought back before the Management Team or individual assiged to develop the resolution to the situation for further action.
Hope this helps.
Cheers!
Mike
