What is the primary focus of the THERP method?

The THERP method, which stands for Technique for Human Error Rate Prediction, primarily focuses on estimating human error rates in various tasks or processes. This method is based on the understanding that human errors can significantly impact safety and operational effectiveness. THERP provides a structured approach to identify potential errors in human activities and quantify their likelihood, which helps in risk assessment and the development of strategies aimed at mitigating those errors.

By estimating human error rates, organizations can gain insights into how human factors influence safety and performance, allowing them to implement effective training, design improvements, or procedural changes to reduce the risk of errors. This approach is crucial in high-stakes industries like aviation, healthcare, and nuclear power, where understanding human contributions to system failures is vital for safety.

While other options relate to important aspects of safety and risk management, they do not align as directly with the primary purpose of the THERP method, which is specifically geared towards understanding human error in operational contexts.
