Original contribution: PQ written by Sven Pommeranz on 3/20/2002 at 08:38) PQ and PV are used in many different and often confusing ways in industry. Often PQ is referred to the long-term qualification of utilities (e.g. WFI over a one year period), whilst PV is used to describe the validation activities for a specific (manufacturing) process. When referring to regulations you should also define in your VMP the terms as they are used within your company.
