Which analysis tool does a Supportability Analysis typically use to identify failure modes, their effects, and criticality?

• A. Risk matrix.
• B. Root cause analysis.
• C. Failure Modes, Effects and Criticality Analysis (FMECA) systematically identifies the likely modes of failure, the possible effects of each failure, and the criticality of each effect on mission completion.
• D. Cost of quality analysis.

Answer: (C)

In supportability analysis, you want a proactive way to uncover how things could fail, what those failures would do to system performance, and how important each failure is to the mission. This is exactly what Failure Modes, Effects and Criticality Analysis does. It methodically lists potential ways a component could fail (failure modes), describes the resulting effects on the system or mission (effects), and assesses how critical each effect is—often by evaluating how likely the failure is, how severe the impact would be, and sometimes how easily the failure could be detected. This ranking lets you prioritize mitigations, add redundancy, plan tests, and shape maintenance strategies to focus on the most mission-threatening risks. Other tools like a risk matrix, root cause analysis, or cost of quality have valuable uses, but they don’t provide this structured, comprehensive view of failure modes, their effects, and their criticality in a single framework.
