Technique for human error-rate prediction
The Technique for human error-rate prediction (THERP) is a technique that is used in the field of Human Reliability Assessment (HRA) to evaluate the probability of human error occurring throughout the completion of a task. From such an analysis (after calculating a probability of human error in a given task), some corrective measures could be taken to reduce the likelihood of errors occurring within a system.
