Fault Tree Analysis (FTA) is a graphical as well as a mathematical tool to analyze the potential for failure for a machine or a system. It is a top-down approach that tries to reverse engineer the root causes of a potential failure. It is used as a part of the root cause analysis process.

What is fault tree analysis all about?

Fault tree analysis (FTA) is a top-down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. ... These system failure conditions and their classification are often previously determined in the functional hazard analysis.

How do you explain fault tree analysis?

Fault tree analysis (FTA) is a graphical tool to explore the causes of system level failures. It uses boolean logic to combine a series of lower level events and it is basically a top-down approach to identify the component level failures (basic event) that cause the system level failure (top event) to occur.
