A Fault Tree Analysis (FTA) is a tool used to identify potential causes of failure in a system. It is a type of logic diagram that uses a tree-like structure to represent the various components of a system and the relationships between them. The purpose of a Fault Tree Analysis is to identify all possible causes of a system failure, including both human and technical errors. The Fault Tree Analysis starts with a single root cause and then branches out to include all possible causes of the failure. The Fault Tree Analysis is a systematic approach to identifying and analyzing potential failure points in a system. It is a valuable tool for understanding the cause and effect of system failures and can be used to develop preventive measures and contingency plans. The Fault Tree Analysis can also be used to evaluate the effectiveness of existing preventive measures and to identify areas for improvement.
