FMEA PROCESS FLOW Causes/ failure mechanisms Product definition Failure modes identification Failure effects Describe Product/process Describe Function Component Subsystem System Damage to equipment Injury to the user Performance degradation of the process Man Method Machine Environment Results Assessment Risk factor calculation Detection methods Actions taken Detect PM plans Tools Checklist Prevent Planned maintenance Actions should: eliminate failure mode eliminate causes Reduce occurences Improve evaluation detection RPN = SxOxD Severity (S) Occurrences (O) Detection (D) Re-calculate RPN after taking actions Re-consider Occurrence (O) Re-consider Detection (D) Unless failure mode is eliminated severity will stay the same
