While not specially said in the FDA PAR or even the Q7A PQR, and only stated briefly during the EU PQR, the PAR/PQR is definitely an Examination to recognize adverse developments and is among the tools for preventive motion as outlined in the corrective and preventive motion (CAPA) method.
Non-compliance: Deviations from established production methods devoid of suitable justifications or investigations.

Process style and design defines the commercial approach determined by improvement know-how. Procedure qualification evaluates the design and decides if the procedure is reproducible. Ongoing method verification makes certain the procedure stays managed during program production. Significant quality attributes and demanding approach parameters are determined, and control techniques are recognized.
