PFMEA Rescoring: How Do You Prove a Corrective Action Actually Lowered Risk?
A PFMEA gets built, signed off, and filed. Six months later a corrective action closes against one of its failure modes, and nobody updates the RPN. Here is how a rescore workflow locks severity, recalculates occurrence and detection, and produces a before and after risk number a PFMEA spreadsheet cannot generate on its own.
DFMEA vs PFMEA: How Design and Process FMEA Divide the Work and Where They Have to Line Up
A DFMEA and a PFMEA are not the same document at two stages of maturity. They analyze different things, are owned by different people, and get kicked back for different reasons. Here is what each one covers, how the AIAG-VDA seven-step method applies to both, and the severity and characteristic links a customer reviewer checks first.
PFMEA Software vs Templates: When Spreadsheets Stop Working
Excel-based PFMEA templates work for one program at a time. They break the moment Action Priority ratings need to propagate to a Control Plan, a process step revision lands mid-program, or three engineers edit the same workbook. PFMEA software solves the propagation problem the AIAG-VDA 2019 handbook now expects you to solve.
