What is the overall purpose of the methods and models such as the Three Levels of Incident Causation Model and Why Method?

• A. To understand how and why incidents happen
• B. To punish responsible individuals
• C. To reduce training requirements
• D. To maximize production

Answer: (A)

Understanding how and why incidents happen. These methods aim to uncover the sequence of events and the deeper factors that lead to an incident, so you can prevent recurrence. The Three Levels of Incident Causation Model helps separate what happened (the immediate triggers) from the conditions that set the stage (underlying factors) and the deeper system weaknesses (root causes). The Why Method uses iterative questioning to trace back from an apparent cause to fundamental contributors, often revealing organizational or management factors that created risk. Together they shift focus from blaming individuals to improving systems, procedures, training, and controls, which reduces the chance of repetition.
