DFMEA 的完成基于设计正式发布或是项目批准。• A Process FMEA is considered “complete” when all inputs from DFMEA are fully considered in the production process, including all the manufacturing/assembly critical X’s, and reflected in the Control Plan, with Error Proofing as necessary. PFMEA 的完成基于来自 DFMEA 的输入全部完成，包括制造 / 装配评定，并反馈到 CP 。（注：防错也包含其中） DFMEA DVP & R PFMEA Pre-Launch Control Plan Production Control Plan Prototype Control Plan Modification of PFMEA (as required) Standard ...
