Decision tree analysis is a technique that uses a graphical representation of various possible outcomes and consequences of different courses of action, based on their probabilities ofoccurrence and associated payoffs or costs. It can help the project team to compare and evaluate the alternatives and choose the optimal one. In this case, the risk manager should use decision tree analysis to help the team members predict the outcomes of their potential choices following their probability of occurrence. Political, economic, social, technological, legal, and environmental (PESTLE) analysis, strengths, weaknesses, opportunities, and threats (SWOT) analysis, and cost-benefit analysis are not techniques that can directly help the team members to predict the outcomes of their potential choices following their probability of occurrence, and are therefore not the best answer.
