fault tree analysis

(programming)
A form of safety analysis that assesses hardware safety to provide failure statistics and sensitivity analyses that indicate the possible effect of critical failures.

The literature provided many options for 'root cause analysis' (RCA), ranging from 5 whys, Ishikawa diagrams, cause and effect matrices to Fault Tree Analysis (FTA).
In the Fault Tree Analysis, it first needs to solve all minimal cut sets (minimal path sets) before calculating the occurrence probability of top events and intermediate events, then using the inclusion-exclusion theorem for precise calculations, or perform approximate calculation through exclusive approximate or independent approximate.

Fault tree analysis (FTA) is used to estimate the probability of an event by establishing the potential cause-and-effect linkages and assigning a probability to these intermediate causes.
We adopted Aghaie's (2004) study which attempts to show the possibility and benefits of using Fault Tree Analysis (FTA) in the area of Total Quality Management (TQM) by presenting and evaluating the relationships among the elements of the ISO 9001:2000 standard and the potential problems and root causes of failure in ISO implementation.
One particularly good aspect of the fault tree analysis is that it seeks to get to the root of any fault problem, so it is not about papering over the cracks, but rather seeks to address why the cracks have occurred and making certain that they do not happen again.
