Human Factors Analysis and Classification Systems



Modern, high-reliability organizations design operations to advance the assurance of desired production results and preclude adverse consequences. Often, they establish complex systems to create boundaries that control risk. Increasing complexity may expand the likelihood, the propagation and the obscurity of human error and increase exposure to the risks of human error. Often, incident investigations end where we believe they should begin – exposing human errors and establishing causal relationships through human factors analysis and classification.
Studying human error allows us to structure, modify, reposition, upgrade and implement barriers to the flow of error, not to prevent human error, but to reduce its probability and prevent its path to failure.

Back to HFACS

HFACS was initially used by U.S. military to investigate and analyze human factors in aviation incidents. In short:

• HFACS guides organizations in the identification of human factors and the development of more meaningful corrective action to prevent incidents from happening before they occur.

• HFACS helps corporations in complex industries improve reliable human performance and organizational resiliency.
