Fault Tree Analysis (FTA)

This is one of the 'Advanced Tools' for Problem Solving.
A Fault Tree Analysis in one of its simplest forms is shown in the following example.
In that, any of the following failures will cause the system to fail:

•Failure of components 1 and 2.

•Failure of components 3 and 4.

•Failure of components 1 and 5 and 4.

•Failure of components 2 and 5 and 3.
