Which analysis is most suitable for identifying root causes of a top-level risk event?

• A. Event tree analysis
• B. Insurance policy evaluation
• C. Fault tree analysis shows logical relationships of component faults leading to the top event.
• D. Risk appetite statement

Answer: (C)

Uncovering the root causes of a top-level risk event requires breaking down the event into contributing faults using a deductive, logic-based approach. Fault Tree Analysis starts with the top event and systematically maps how various component failures and conditions combine through AND and OR relationships to produce it. This downward, cause-and-effect structure reveals which basic events are responsible and which combinations are necessary or sufficient, making it possible to target specific failures or design weaknesses for mitigation. Event tree analysis, in contrast, looks at possible sequences of outcomes from a starting initiating event and is more forward-looking, focusing on consequences and probabilities of different paths rather than the underlying causes that lead to the top event. Insurance policy evaluation centers on terms and coverage, not on why a risk event occurs. A risk appetite statement defines the level of risk an organization is willing to accept, not the mechanical identification of root causes.
