  2. 2. FMEA Introduction To FAILURE MODE EFFECTS & ANALYSIS
  3. 3. definationFMEA is a procedure in product development and operations management for analysis of potential failure modes within a system forclassification by the severity and likelihood of the failures.
  4. 4. FMEA cycle

  6. 6. Example of FMEA
  7. 7. Example of FMEA
  8. 8. Example of FMEA Severity of Effect10 May result in safety issue or regulatory violation withoutwarning9 May result in safety issue or regulatory violation with warning8 Primary function is lost or seriously degraded7 Primary function is reduced and customer is impacted6 Secondary function is lost or seriously degraded5 Secondary function is reduced and customer is impacted4 Loss of function or appearance such that most customerswould return product or stop using service3 Loss of function or appearance that is noticed by customersbut would not result in a return or loss of service2 Loss of function or appearance that is unlikely to be noticed bycustomers and would not result in a return or loss of service1 Little to no impact Some organizations such as SAE, AIAG, ISO 9000, and ISO/TS 16949:2002 have established severity ratings.

Example of FMEALikelihood of Detection10 Absolutely uncertain that failure will be detected9 Very remote chance that failure will be detected8 Remote chance that failure will be detected7 Very low chance that failure will be detected6 Low chance that failure will be detected5 Moderate chance that failure will be detected4 Moderately high chance that failure will be detected3 High chance that failure will be detected2 Very high chance that failure will be detected1 Almost certainty that failure will be detected
