Decision Trees

Identifies options available and key choices.
Analysis of complex decisions with significant uncertainty can be confusing because:

• the consequence that will result from selecting any specified decision alternative cannot be predicted with certainty.
• there are often large number of different factors that must be taken into account
• may be useful to consider possibility of reducing uncertainty in the decision by gathering additional information
• decision makers attitude toward risk taking can impact relative desirability of alternatives

Provide effective structure – lay out options and investigate possible outcomes of choosing those options.
Help form balanced picture of risks and rewards associated with each possible course of action.
