abstract="This article describes the process of socio-technical probabilistic risk assessment (ST-PRA). What makes ST-PRA an evolutionary step is that the entire risk model is made up of human errors and at-risk behaviors, attempting to model the as-is state of a predominantly human process. Where traditional PRA will generally model a technical system with some input of human errors (e.g., THERP or WASH 1400; Kanki & Marx, 2004), the ST-PRA attempts to model human errors and human variations, where, given behavioral norms, 1 task can be performed many different ways within 1 risk model. ST-PRA is an attempt to model complex human variation in the way we perform our work.<p />",
