Fault Tree Analysis is the method that employs deductive reasoning, which involves starting with a high-level event (usually an undesirable outcome) and working backward to identify the possible causes. This approach allows practitioners to visualize the pathways that can lead to failures and assess contributing factors systematically. By prioritizing risks and focusing on root causes, Fault Tree Analysis helps in understanding how different factors can interrelate to produce a negative outcome, facilitating targeted risk management strategies.

The other methods involve different approaches. Failure Mode Effects Analysis emphasizes proactive identification of potential failure modes and their effects rather than working backward from an undesired event. Job Hazard Analysis is a step-by-step job or task evaluation process that focuses on identifying hazards before the task begins, rather than analyzing a failure after the fact. What-If Analysis involves brainstorming potential problems and is more exploratory than deductive, relying on the creativity of participants to generate possible adverse scenarios. Thus, Fault Tree Analysis stands out for its systematic deduction of causes from a specified event.
