ETA

is a technique to illustrate or quantify the various events that may follow from one initiating event. [10]

A method of exploring the development or escalation of an accident, a failure or an unwanted event using a diagram which, commencing with the initiating event, branches at each point of influence of a controlling or mitigating measure until the final outcomes are identified. The probability (or frequency) of success of these measures is indicated allowing for the evaluation of the likelihood of each consequence. [12]
