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 failure, and branches down to its causes. Each branch represents a different pathway that can lead to the failure, helping engineers and safety professionals understand the relationships between different components. FTA is commonly used in fields like engineering, aviation, and nuclear safety to improve reliability and safety. By identifying potential faults early, organizations can implement preventive measures, reduce risks, and enhance overall system performance.
