Transcript

  • 1. FMEA - Failure Modes and Effects Analysis Michael Bauer Jarrod Redden Justin Weaver
  • 2. Purpose of FMEA
    • Failure Modes and Effects Analysis provides a framework for analyzing potential reliability problems early on in design.
    • The FMEA framework is used to identify and prioritize possible points of failure, determine their effect on the product’s operation, and identify actions to reduce potential failures.
  • 3. FMEA Operational Definitions
    • Failure Modes – Ways in which the solution might fail
    • Severity – Likely impact of the failure
    • Occurrence – Probability that potential cause will happen
    • Detection – Likelihood current controls will detect failure
    • Risk Priority Number (RPN)
      • Severity x Occurrence x Detection
  • 4. Comparison Matrix - FMEA Analysis
  • 5. FMEA Best in Class Template Features
    • Sort Capability for Severity, Occurrence, and Detectability fields
    • RPN Charting – bar chart sorts RPN in descending order
    • Priority Field – can be used as a manual override after charting and sorting the FMEA template by RPN
    • FMEA Resolution tab – displays actions taken and new RPN values. These can be sorted and the process can be restarted
  • 6. Comparison Matrix – Scale Analysis
    • Degree of Severity, Probability of Occurrence, and Detectablility are ranked on a 1-10 scale.
