The correct answer isB. It can only be used to identify single failure modes and can become time-consuming and complex for multi-layered systems. FMEA is a structured technique used to identify potential failure modes, their causes, and effects. While powerful, it has known limitations, particularly when applied tocomplex systems with many interdependencies.
FMEA typically examines failure modes one at a time, which makes it less effective at capturing interactions between multiple failures or system-wide cascading effects. As system complexity increases, FMEA can becomeresource-intensive and time-consuming, requiring extensive effort to analyze all components and failure scenarios.
Option A is incorrect because FMEA can be quantitative or semi-quantitative and is often used to rank risks using severity, occurrence, and detection ratings. Option C is incorrect, as FMEA is widely used in technical and engineering contexts. Option D is incorrect because FMEA explicitly analyzes the effects and consequences of failures.
From a PECB ISO 31000 Lead Risk Manager perspective, understanding the limitations of risk assessment techniques is essential for selecting appropriate tools. FMEA is valuable but should be complemented with other techniques when dealing with complex or highly interconnected systems. Therefore, the correct answer isoption B.
