In many cases there are multiple causes for an accident or other loss-making event. Fault tree analysis is one analytical technique for tracing the events which could contribute. It can be used in accident investigation and in a detailed hazard assessment. The fault tree is a logic diagram based on the principle of multi-causality, which traces all branches of events which could contribute to

Event tree analysis (ETA) is a forward, bottom up, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes and overall system analysis. 3.1 In a Fault Tree the TOP event of the tree is a system failed state or a system failure event and the PRIME events of the tree are element states and events that cause the system failure (and are usually element failures).
