Fault tree analysis is a graphical representation of the major faults or critical failures associated with a product, the causes for the faults, and potential countermeasures. The tool helps to identify areas of concern for new product design or for improvement of existing products. It also helps users identify corrective actions to correct or mitigate problems.

Suppose that we visit the courthouse in a certain town, and we observe people who stop at the office of the local justice of the peace to register their marriages. Let A be the independent probability of finding in the office an adult woman who is going to get married (i.e., female spouse), while B is the probability of finding a marrying adult man (i.e., male spouse). We disregard any liaison between staff members who are employed in that office in order to be free of bias in our experiment.
The following fault tree diagram was created and included in the Edraw example gallery.

Fault tree analysis is useful both in designing new products/services or in dealing with identified problems in existing products/services. In the quality planning process, the analysis can be used to optimize process features and goals and to design for critical factors and human errors. As part of process improvement, it can be used to help identify root causes of trouble and to design remedies and countermeasures.
