Fault Tree Analysis (FTA) is a systematic, deductive failure analysis technique used to determine the various combinations of hardware and software failures, human errors, and other factors that could lead to a specific undesirable event (referred to as the "top event") in a system. FTA is widely used in process safety management to identify and mitigate potential risks in complex industrial processes. By constructing a fault tree, organizations can visualize and understand the pathways through which failures could occur, enabling them to implement more effective safety measures.
