Diagramming technique Decision tree analyses are commonly used when certain risks have an exceptionally high impact on the two main project objectives: time and cost (Heldman, 2005). There are two types of decisions trees; called Fault tree analysis (FTA) and Event tree analysis (ETA).The FTA method of analysis is used to determine the probability of the risk and is used to identify risks that can contribute or cause a failure of one event (Cooper et al. 2005). The purpose is to find the underlying causes to this event. It is usually drawn up as a sketch of a tree. The branches are the causes to the problem, and the starting point of the tree is the problem itself. Each branch has its own sequence of events and possible outcomes. The problem could depend on some causes that are interrelated with each other, or simply random.
