Process Validation
Demonstrating that a process, within set parameters, can effectively and reproducibly produce product meeting its specification and quality attributes.
Details
Process validation demonstrates, from process design through continued verification, that the commercial process reproducibly achieves the predetermined quality attributes. Inspections cite batches that are not representative, worst case conditions and process variability not evaluated, and no trend monitoring after PPQ. Look at process design knowledge, the PPQ protocol and batch data, statistical trends, deviations and changes, and the continued process verification report.
