- A human reliability analysis is a systematic evaluation of the factors that influence the performance of the operators, maintenance staff, technicians, and other plant personnel. It involves one of several types of task analyses; these types of analyses describe a task’s physical and environmental characteristics, along with the skills, knowledge, and capabilities required of those who perform the tasks. A human reliability analysis will identity error-likely situations that can cause or lead to accidents. A human reliability analysis can also be used to trace the cause of human errors. Human reliability analysis is usually performed in conjunction with other hazard evaluation techniques.
