FMEA and control plan: turning failure modes into a reaction plan
An FMEA that lives in a spreadsheet and never changes protects nobody. This guide walks through DFMEA and PFMEA, how the RPN = severity × occurrence × detection score flags special characteristics, and how each of those characteristics carries onto the control plan — with its specification, the calibrated gauge, the sample frequency, the method and the reaction when a reading goes out of tolerance. Plus how a CAPA re-evaluates the RPN so the FMEA stays a living document.
Gauge calibration and MSA / Gauge R&R: making measurements you can trust
Every acceptance decision, Cp/Cpk number and dimensional result rests on one assumption — that the gauge is telling the truth. This guide covers the gauge register and gauge types, the calibration cycle (due → sent → calibrated → returned) with next-due tracking for clause 7.1.5 evidence, and MSA — bias, linearity, stability and Gauge R&R that separates gauge variation from operator variation. Plus what to do when a gauge fails: quarantine it and recall the suspect measurements it produced.
8D and CAPA: closing out a customer complaint or rejection properly
A rejection or a customer complaint that gets a one-line email reply comes back. This guide follows the eight disciplines — D1 team through D8 closure — with containment, root cause and permanent corrective action, and shows how the CAPA is driven through change management so it actually amends the FMEA (RPN) and control plan and, where needed, triggers a PPAP re-submission. Defect codes are the common language that ties a line rejection back to the failure mode that predicted it.
