FMEA – Failure Mode and Effect Analysis

Definition

A methodology to identify, quantify, prioritize and evaluate potential failure mode

Terms

Failure mode: What could go wrong

Effect analysis: How would it happen, how likely is it to go wrong, how bad would that be

Goals

  1. Reduce risk of failure
  2. Ensure failures are detectible
  3. Prevent failure from happening.

Prevention: A way to figure out what can go wrong and what can be done in order to avoid it

When

Ahead of time or during the project lifecycle when a potential risk is discovered

We do FMEA for procedures that can be risky or costly

Why

Preventing problem is cheaper than cleaning it

Some things are too risky or costly to incur mistakes

How

Gather all relevant participants from several verticals to give their insight of potential risks

  1. Analyze risks
  2. Define the most critical and include them in the control plan

Define potential failure mode for each Process (can have several failure modes)

  • Cause of failure (Root cause) – what might cause this failure mode
  • Effect of failure (Impact of failure)
  • Current control – what is done today in order to prevent the failure
  • Hazard Score (RPN=Risk Priority Number, is the product of Severity, Occurrence, and detection rating)
    • Occurrence/Probability (how likely to occur) [F]
    • Detection [D]
    • Severity [S]
  • Prevention/Mitigation/Control (recommended actions)
  • Revised RPN – after hazard mitigation
