12 Comprehensive Chapters
Each chapter builds your fmea expertise systematically from foundations to advanced application.
Introduction to FMEA
Understand what FMEA is, why it matters, and how it fits into automotive product development and ISO 26262.
FMEA Fundamentals
Learn core FMEA concepts: failure modes, effects, causes, controls, and the risk priority framework.
AIAG/VDA 7-Step Process
Walk through the unified AIAG/VDA FMEA methodology step-by-step with practical guidance at each stage.
Design FMEA (DFMEA)
Apply DFMEA to identify and mitigate product design failure modes before hardware release.
Process FMEA (PFMEA)
Apply PFMEA to manufacturing and assembly processes to prevent production-induced failures.
Rating Criteria: S, O, D Scales
Master the Severity, Occurrence, and Detection rating criteria with automotive-specific examples for consistent scoring.

DFMEA for an ASIL-C Electronic Throttle Control (ETC) Module
Walk through a complete DFMEA for an Electronic Throttle Control module, from function analysis through action prioritization and ISO 26262 integration.
- Function analysis: 12 functions, 34 failure modes identified and rated
- Failure net: throttle stuck-open path traced through 4 effects to vehicle level
- SPF analysis identified 2 single-point failure candidates requiring design changes
- Diagnostic coverage mapped: 89% DC achieved for ASIL-C hardware requirements
- Action log: 6 priority actions reduced AP from H to L within 4-week design iteration
