Many techniques can be used to find the root causes of asset failures and other important events we want to analyze. Fault tree analysis is one of those techniques, and it is being utilized by many different companies to improve system reliability.

This guide aims to give a basic to intermediate introduction to the fault tree analysis process. It discusses uses cases, types, symbols, processes, examples, and helpful software solutions.

What is fault tree analysis?

Fault tree analysis (FTA) is a graphical as well as 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.
