FMEA / FMECA Risk Worksheet

Rank system failure modes by risk priority and assign mitigation actions with XLSX/PDF exports.

How does modern Action Priority (AP) differ from classic RPN?

Traditional FMEA multiplies RPN = S × O × D. However, AIAG-VDA 2019 replaced RPN thresholds with Action Priority (AP) tables because high-severity hazards (e.g. S=9 or 10) must never be hidden by low detection or occurrence ratings.

FMEA & FMECA in Maintenance Strategy

Failure Mode and Effects Analysis (IEC 60812) is the cornerstone of proactive reliability engineering. It systematically evaluates potential failures, quantifies operational and safety risks, and directs maintenance tasks toward mitigating catastrophic single points of failure.

Frequently Asked Questions

What is the difference between FMEA and FMECA?

FMEA is qualitative; FMECA adds Criticality Analysis (C) which factors in operating time and failure rate (MIL-STD-1629A).
