ABSTRACT
A human interacting with a system can be analysed to determine the errors that could occur, what factors could help mitigate these errors, and the probability of these errors occurring. This is done by using human reliability assessments (HRA). HRA techniques have accounted for factors that influence the error probability in the form of “performance shaping factors”. The task, the individual and the environment define the performance shaping factors. The tool being validated will be looking at a team of people that are either interacting with the same system or piece of equipment, and whose procedures are all critical in achieving the same overall goal. There are three main aspects that can cause error; the task, the environment and the individual. There are several types of errors that humans can perform, such as execution errors, or errors of cognition.
