Failure mode and effects analysis: Process and system risk assessment

Failure mode and effects analysis (FMEA) is widely used by corporations, manufacturing firms and the U.S. military to evaluate processes or systems (e.g. an incident-response process or a three-tiered application). It prioritizes potential failures by impact severity, probability of occurrence and likelihood of detection.

FMEA risk ratings and narrative rationale can be used to quantify exposure to management and facilitate remediation. Most recently, FMEA was incorporated into Six Sigma and the Information Technology Infrastructure Library (ITIL).
