What is the main distinction between a high-level risk assessment and a detailed FMEA?

• A. A high-level risk assessment identifies major risk categories; FMEA provides granular, step-by-step evaluation of specific failure modes and effects.
• B. A high-level risk assessment analyzes every specific failure mode in detail.
• C. FMEA identifies broad risk categories without considering specific failures.
• D. They are identical in depth and scope.

Answer: (A)

The main idea is the difference in scope and detail between screening for big-picture risks and doing a full, failure-focused analysis. A high-level risk assessment looks across the system or process to identify major risk categories and rough risk areas. It’s quick, broad, and helps you decide where to focus deeper investigation. A detailed FMEA, on the other hand, dives into specific components or steps, listing each potential failure mode, its effects, causes, and existing controls, and then evaluates severity, likelihood, and detectability to prioritize actions with a granular, step-by-step examination.

That makes the best choice correct because it captures this contrast: the high-level approach highlights broad risk categories, while FMEA provides a granular, failure-mode–level analysis. The other statements mix up the levels of detail or claim they’re identical, which doesn’t fit how these tools are used in practice.
