What is the goal of the "SHEL" model in human factors?

The "SHEL" model, which stands for Software, Hardware, Environmental factors, and Liveware, focuses on understanding the interactions between these components in human factors and how they contribute to safety and performance in aviation and other industries. The primary goal of the SHEL model is to identify where and why problems exist within these interactions. By analyzing the various elements involved—human (liveware), technology (hardware and software), and environment—stakeholders can pinpoint specific issues that may lead to errors or inefficiencies. This approach is crucial for improving systems, optimizing performance, and enhancing safety.

Identifying the root causes of problems allows organizations to implement effective solutions, foster a safer workplace, and minimize the risk of accidents. This framework encourages a holistic view of human factors, emphasizing the importance of considering all components and their interactions in the analysis process.
