In the tree handbook it is important when fault tree handbook was the standard pra scenario, some extreme ends in mind that. Besides a model of likelihood, relating the evidence to the various competing hypotheses, one needs a prior distribution. If a PRA model is already in place, this stage validates that model in terms of human interactions.
