Type of Validation



Prospective Validation
Validation conducted before the distribution of either a replacement product or product created beneath a revised manufacturing methodology, where the revisions may affect the Product’s characteristics.

This method is effective only if the development stage has resulted in a proper understanding of the fundamentals of the process. The first three production –scale batches must be monitored as comprehensively as possible.
Concurrent validation beside a Associate in Nursingalysis|analysis|analytic thinking} together with stability ought to be applied to an acceptable extent throughout the lifetime of the product.
Retrospective Validation
Validation of a method for a product already in distribution primarily based upon accumulated production, testing and control data.
Yes, you can! But regulators do not like!
         Must be robust process
         No unexplained failures
         More than 30 consecutive acceptable batches
         Must use statistical analysis
         Use Cp and Cpk (Process capability)
