Failure Mode and Effects Analysis (FMEA)
Failure Mode and Effects Analysis (FMEA) is a systematic, bottom-up technique for identifying the ways in which components, processes or systems can fail, the effects of those failures and the actions that can mitigate them. It originated in 1940s US military reliability engineering (MIL-P-1629) and is now codified in IEC 60812 and IEC 31010.
Process
Define the system boundary — the equipment, sub-system or process under review.
List functions — what each component is supposed to do.
Identify failure modes — how each function could fail.
Identify effects — local effect on the sub-system, next-level effect, end effect on the customer or business.
Identify causes — the mechanisms that could trigger each failure mode.
Identify current controls — preventive and detective.
Rate severity, occurrence and detection — each typically on a 1–10 scale.
Identify recommended actions for the highest-RPN failure modes.
Variants
Design FMEA (DFMEA) — at design stage of a product.
Process FMEA (PFMEA) — for manufacturing or service processes.
System FMEA — at architectural level.
FMECA — adds Criticality analysis for a more quantitative assessment.
Commercial insurance relevance
FMEA is referenced in product liability, recall and professional indemnity proposal forms — particularly for medical devices, automotive, food, aerospace and engineering risks. Evidence of disciplined FMEA can shift terms materially.

Our service promise. We acknowledge every quote request the same working day. For straightforward risks, indicative terms typically follow within five working days. Complex risks — higher-risk buildings, cladding, mid-term proposals requiring fresh underwriting — may take longer; we’ll send you a progress note by the end of the fifth working day in those cases.
