Fault Tree Analysis (FTA) is a systematic method used to identify and analyze potential failures in a system. It visually represents the various ways a system can fail, using a tree-like diagram that starts with a top event, or undesired outcome, and branches down to its causes. Each branch represents a different failure mode, allowing engineers to understand how different factors contribute to the overall risk. FTA is commonly used in fields like engineering, safety analysis, and risk management. By identifying the root causes of failures, organizations can implement preventive measures, improve system reliability, and enhance safety protocols.
