FMEA

FMEA

1. Failure Mode & Effects Analysis

2. looks at design in its entirety

3. each sub systems is considered

4. Specific failure modes are discovered

5. Causes are identified

6. Effects of failure modes are identified

7. Rated based on severity, occurrence, detection

8. RPN = S x O x D

9. Recommendations made ie. test, redesign, etc

10. Rescored based on recommendation

    • RPN redone

11. Lead to better design has failure modes can be designed out
