FTA, short for Fault Tree Analysis is a tool from quality management used to capture and represent potential cause-and-effect relationships, often employed in Root Cause Analysis. It is primarily used in aerospace, nuclear industries, and chemistry. Fault Tree Analysis is a structured top-down tool for identifying faults, based on Boolean logic: an event or undesired outcome is represented as a result of various basic and intermediate events, with failure probabilities assigned to individual basic events.
