The FMEA Guide: The Methodology Behind Design, Process, and Use FMEAs for Medical Device and Regulated Manufacturing (The Quality Systems Series Book 4)

The methodology behind defensible risk analysis.FMEA is the backbone of ISO 14971 — and the place where most design and process reviews come apart. Most FMEA references are written for automotive plants or generic manufacturing. This guide is written for the medical device team — quality managers, design engineers, process engineers, and supplier quality leads who have to defend their RPN priority decisions to a Notified Body inspector and need the methodology to be right.Written by a working manufacturing quality professional, this is the thinking behind every column on the worksheet — the calibration discipline behind every score, and the regulatory reasoning behind every action priority decision. Twelve chapters move from theory to practice with worked examples a Notified Body will recognize.INSIDE THIS GUIDEThe four FMEA types — DFMEA, PFMEA, Use FMEA, and System FMEA — and when to use eachFull walkthroughs of Severity, Occurrence, and Detection rating scales calibrated for medical-device criteriaThe RPN trap: why a high-severity, low-RPN failure still forces action — and why Severity 9 or 10 always overrides the priority mathA completed catheter-hub DFMEA walked end-to-end, pre- and post-mitigation RPN math (180 / 189 / 105 / 96 → 36 / 36 / 42 / 32)Use FMEA and IEC 62366-1 — usability engineering for medical devices, the variant most FMEA books skip entirelyLinking FMEA to Control Plans, Design History Files, and Risk Management Files for audit readinessRegulatory cross-walk: ISO 14971, ISO 13485, 21 CFR 820, EU MDR, and AIAG-VDA harmonized in one referenceEleven anti-patterns that recur across inherited FMEA portfolios — and the remediation move for each Most FMEA books stop at the spreadsheet. This one teaches you how to defend it out loud — when the inspector pulls the document, when a Severity-9 row sits at RPN 56, when an inherited portfolio looks credible on the surface and falls apart on the third question.Companion workbook: FMEA Risk Analysis Workbook by Wade Prescott — the bench-ready template that turns this methodology into completed cycles. Both books reinforce the same catheter-hub DFMEA so the guide and the workbook read as one system.Part of The Quality Systems Series by Wade Prescott. Read more
