Tripod Beta Analysis in Incident Investigation
The tripod method is a way of conducting incident analysis. It is mostly used for high risk, complex incidents, since it is a very extensive and detailed method. In order to construct an effective tripod beta investigation and analysis, training is highly recommended.
A Tripod Beta tree is built in three steps :
- The first step is to ask the question: what happened? All the events that happened in the incident are listed as a chain of events.
- The next step is to identify the barriers that failed to stop this chain of events. The question that is asked in this step is: How did it happen? When all the events and the failed barriers in between are identified, the reason for failure of these barriers is analyzed.
- The last question for this step is: Why did it happen? For each of the failed barriers, a causation path is identified.
