Which statement about the SHEL model is correct?

Which statement about the SHEL model is correct?

• A. It Focuses Exclusively on Hardware Components
• B. It Ignores Human Factors
• C. It Aims to Determine Not Only What the Problem Is, But Also Where and Why It Exists
• D. It Only Analyzes Past Incidents

Answer: (C)

The SHEL model is a framework for analyzing safety in complex systems by looking at how four parts interact: Software, Hardware, Environment, and Liveware (the people involved). It emphasizes that problems arise from the interfaces and interactions among these components, not from a single piece in isolation. This is why the best statement is that the model aims to determine not only what the problem is, but where and why it exists—by tracing how software, hardware, the surroundings, and human factors come together to produce a issue. The model includes human factors through Liveware, so it’s not about ignoring people, and it’s not limited to hardware or to analyzing only past incidents.
