Fault Tree Analysis


Fault Tree Analysis (FTA) is a technique for reliability and safety analysis. Bell Telephone Laboratories developed the concept in 1962 for the US Air Force for use with the Minuteman system. It was later adopted and extensively applied by the Boeing Company. Fault tree analysis is one of many symbolic "analytical logic techniques" found in operations research and in system reliability. 
A fault tree diagram is used to conduct fault tree analysis (or FTA). Fault tree analysis helps determine the cause of failure or test the reliability of a system by stepping through a series of events logically.

A fault tree creates a visual record of a system that shows the logical relationships between events and causes lead that lead to failure. It helps others quickly understand the results of your analysis and pinpoint weaknesses in the design and identify errors.

A fault tree diagram will help prioritize issues to fix that contribute to a failure.

The fault tree diagram creates the foundation for any further analysis and evaluation.

You can use a fault tree diagram to help you design quality tests and maintenance procedures.

The following is an example of a Fault Tree diagram.
