FAULT TREE ANALYSIS – Kaizen Chronicles

28/11/2020· Fault tree analysis (FTA) is a Risk Management tool that identifies the safety-critical functions within a system's architecture and design. It is a systematic method of analyzing complex system failures. It examines the system from top to down for any deductive failure. In other words, it helps in analyzing higher level failures and identifies all
