Purpose of process flow diagram after APQP
Does the process flow diagram have any purpose after APQP is complete? Once the cell is up, running and stable, does the PFD become a “non-living document” (unlike the PMEA and Control Plan-which continue on as “living documents”)?

The process flow diagram is one of the first documents to be prepared for process design in the new product launch process. As you know, it starts from the incoming inspection of the product and should show all stages in order until the product is shipped to the customer. It is prepared before PFMEA and the process flow sequence should be the same as the PFMEA and control plan. If there is any change in the process flow, the flow diagram, PFMEA, Control Plan must change accordingly. Therefore, it is a living document and should be followed by revision number, date, etc.
