1. Summary Procedures for FMEA and FMECA
A. Steps for Performance of Analysis- Decide whether FMEA or FMECA is required.
- Define system boundaries for analysis.
- Understand system requirements and function.
- Define failure/success criteria.
- Determine each item’s failure modes and their failure effects
and record these. - Summarize each failure effect.
- Report findings.
B. Additional Steps To Be Taken For FMECA- Determine system failure severity classes.
- Establish item’s failure mode severity.
- Determine item’s failure mode and effect frequencies.
- Determine failure mode frequencies.
- Draw up criticality matrix for item failure modes.
- Summarize the criticality of failure effects from the criticality
matrix. - Draw up the criticality matrix for system failure effects.
- Report findings at all levels of analysis.
NOTE: Quantification of failure mode and effect frequencies may be
undertaken in an FMEA by carrying out steps 8, 9, and 10.
