Toyota's Advanced GD3 Method: Going Beyond FMEA to Build Defect-Free Products
Most engineers know FMEA (Failure Mode and Effects Analysis). But fewer know that Toyota developed an advanced model that goes further. Their engineers created DRBFM - Design Review Based on Failure Modes, founded on the philosophy of GD3 Good Design, Good Discussion, Good Analysis.
This book explains how Toyota uses DRBFM as a practical extension of FMEA during the design phase, where up to 80% of product quality is determined. Instead of repeating a generic FMEA, DRBFM zeroes in on design changes, asking: What could go wrong because of this change?
What you'll learn:
- The history of FMEA and why Toyota created DRBFM.
- The GD3 philosophy: how Good Design, Good Discussion, and Good Analysis work together.
- A clear comparison of FMEA vs. DRBFM - where they overlap and how Toyota's method goes beyond.
- Step-by-step FMEA refresher to build the foundation.
- Case studies (fire extinguisher, electrical steering, car engine) showing DRBFM applied in practice.
- Worksheets and examples to help you run your own design reviews.
Whether you are a design engineer, quality manager, lean six sigma practitioner, or reliability professional, this book gives you the Toyota-proven toolset for embedding quality at the design stage - reducing defects, lowering cost, and creating products that last.
Key difference:
FMEA looks everywhere for risk. DRBFM focuses the discussion exactly where design changes happen, preventing failures before production.
If you've ever thought "FMEA is useful, but too broad" - DRBFM is the focused, Toyota-proven answer.
