FMEA Analysis Cycle

  1. 1. FMEA – Analysis Cycle Control Tool to prevent / detect failures Anand Subramaniam

  3. 3. FMEA – Analysis Cycle FMEA Cycle Step 1 – Detect Failure Mode Step 5 – Risk Priority Number Step 2 – Severity Number Step 3 – Probability Number Step 4 – Detection Number Step 6 – Action & Follow-up
  4. 4. Potential Failure Mode For each process input, determine the ways in which the input can go wrong - the failure modes
  5. 5. Potential Failure Effects For each failure mode, associate the inputs and determine the effects of the failures on the customer
  6. 6. Potential Failure Causes Identify potential causes of each failure mode
  7. 7. Current Controls – Prevent / Detect List the current controls for each cause or failure mode (Prevent / Detect)
  8. 8. Rating Scales - Severity <ul><ul><ul><ul><li>Severity = importance of effect on customer : 1= Not Severe, 10= Very Severe </li></ul></ul></ul></ul>
  9. 9. Rating Scales - Occurance <ul><ul><ul><ul><ul><li>Occurrence = frequency in which a given cause occurs and creates Failure Mode : 1= Not Likely, 10= Very Likely </li></ul></ul></ul></ul></ul>
  10. 10. Rating Scales - Detection <ul><ul><ul><ul><ul><li>Detection - Prevent the causes or failure mode from occurring 1= Likely to Detect, 10= Not Likely at all to Detect </li></ul></ul></ul></ul></ul>
  11. 11. Risk Priority Number <ul><ul><ul><ul><ul><li>Risk Priority Number (RPN) = Severity (effect) X Occurrence (causes) X Detection (controls) </li></ul></ul></ul></ul></ul>
  12. 12. Recommendation Determine recommended actions to reduce high RPN’s
  13. 13. Process Capability
