In the SHEL model, which statement best describes the goal?

• A. To Identify the Responsible Person in an Incident
• B. Not Only What the Problem Is, But Also Where and Why It Exists
• C. To Evaluate the Cost of Safety Improvements
• D. To Predict Future Incidents Using Historical Data

Answer: (B)

The SHEL model focuses on understanding safety issues by looking at how the four components—Software (procedures and information), Hardware (equipment), Environment (physical and organizational setting), and Liveware (people)—interact within a system. The goal is to identify not only what the problem is, but where in the system it exists and why it happened, so underlying causes across the whole system can be addressed. That makes the description about not only what the problem is but also where and why it exists the best fit. The other options miss this systemic perspective, focusing instead on blaming individuals, weighing costs, or predicting incidents.
