In HRA, human actions are typically categorized by when they occur in relation to a system disturbance:

Latent errors committed during maintenance, testing, or calibration that leave a system in an unavailable state before an event occurs. Module 4: Introduction to Human Reliability Ana...

Human Reliability Analysis is a structured, engineering-based discipline used to identify, model, and quantify potential human failure events (). While hardware components are often considered stable until a failure occurs, human performance is inherently dynamic, adaptive, and influenced by a variety of internal and external factors . engineering-based discipline used to identify
