The Human Factors Analysis and Classification System (HFACS) identifies the human causes of an accident and offers tools for analysis as a way to plan preventive training.[1] It was developed by Dr Scott Shappell of the Civil Aviation Medical Institute and Dr Doug Wiegmann of the University of Illinois at Urbana-Campaign in response to a trend that showed some form of human error was a primary causal factor in 80% of all flight accidents in the Navy and Marine Corps.[1]

HFACS is based in the "Swiss Cheese" model of human error[2] which looks at four levels of human failure, including unsafe acts, preconditions for unsafe acts, unsafe supervision, and organizational influences.[1]. It is a comprehensive human error framework, that folded Reason's ideas into the applied setting, defining 19 causal categories within four levels of human failure.[3]
