Must follow flow of the process flow diagram. ? Must include ALL process special characteristics (as a minimum). How a PFMEA Works ? Where does the data for the PFMEA e from? ? What types of people are a part of the PFMEA team? ? What types of activities should we spend a lot of time on? PFMEAs/Control Plans and 8Ds During APQP ? PFMEAs should be driven by real data, including 8Ds (internal and external), warranty and returned part analysis ? PFMEAs should be pleted by process experts and should be a driver of the control plans and work instructions ? Work instructions (Post control log, process parameter logs, preventive maintenance, etc.) implement the control plan in the process ? When there is a quality problem there is an opportunity to improve the control plan and the work instructions APQP Links to Control Plan F i r s t/ L a s t Pi e c eM i s ta k e Pr o o fi n gC o n tr o l Pl a nP/ M C h e c k l i s tQ u a l i ty C h e c k l i s tControl Plans ?
