My confusion is that we do 3 batches for PV .
But new approach for life cycle of product and proces is that continuous verification how ? Which tool will be used for continuous verification.

Dear All,
Also, As per life cycle approach of process validation,
How we can implement continued cleaning process verification, what is the strategy and how to plan it, how much batches to be considered?what will be testing requirements!?
