Failure Mode And Effect Analysis
Failure Mode and Effect Analysis (FMEA) is a systematic technique for identifying potential failure modes, evaluating their effects, and prioritizing actions to reduce risk.
“A systematic approach to risk identification and analysis of identifying possible modes of failure and attempting to prevent their occurrence.”

FMEA helps teams anticipate failures before they occur by analyzing possible failure scenarios, their causes, consequences, and appropriate mitigation strategies.
Proactive analysis: Performed before failures occur.
Risk prioritization: Failure modes are ranked based on severity, occurrence, and detection.
Preventive focus: Results guide design and testing improvements.
Real World Example
A hospital medication system shows a different dosage warning in test than the one specified by the clinical safety rule.
The team needs precise language to separate what was observed, what should have happened, and whether the difference represents a reportable issue. Failure mode and effect analysis provides that distinction.
The tester records the steps, data, observed behavior, expected behavior, and evidence so triage can focus on patient safety impact instead of vague descriptions.
The issue is handled faster because Failure mode and effect analysis helps everyone discuss the problem using a shared testing vocabulary.
