Project managers make important decisions every day. But how can you be sure that the choices you\u2019re making are the best ones for both your career and your company as a whole? The answer is found through decision tree analysis.<\/strong><\/span><\/p>\n

In this article, you\u2019ll learn exactly what decision tree analysis is and why this exercise can benefit project managers. We\u2019ll then show you a four-step system to make effective decision trees.\u00a0<\/span><\/p>\n

What\u2019s a decision tree?<\/span><\/h2>\n

A decision tree is a diagram that clearly defines potential outcomes for related choices.<\/strong> <\/span><\/p>\n

In project management, a decision tree analysis exercise allows project leaders to easily compare different courses of action against each other and evaluate the risks, probabilities of success, and potential benefits associated with each.<\/span><\/p>\n

A proper decision tree has four main elements<\/span>:\u00a0<\/span><\/p>\n

    \n
  1. Decision nodes:<\/b> A decision node, represented on our decision tree diagram as a square, indicates a choice that needs to be made.<\/span><\/li>\n
  2. Chance nodes:<\/b> A circle represents a chance node and is used to signify uncertain outcomes. These nodes are used when future results are not guaranteed.<\/span><\/li>\n
  3. End nodes:<\/strong> End nodes represent the end of a diagram and illustrate an outcome.<\/span><\/li>\n
  4. Branches:<\/b> They connect the nodes. Each branch represents a potential choice and should be clearly labeled.<\/span><\/li>\n<\/ol>\n

    Generally, a decision tree analysis exercise begins with a single decision node, known as a square<\/strong>. From there, branches are drawn, representing various choices and resulting in potential outcomes (i.e., chance nodes).<\/span><\/p>\n

    When the full potential scenario has been played out, an end node is used to signify the outcome. As you\u2019ll see later in this article, a completed decision tree analysis graph looks like a tree, hence the name.<\/span><\/p>\n

    The benefits of doing decision tree analysis<\/span><\/h2>\n

    As a project manager<\/a>, every decision presents new threats and fresh opportunities. The decision tree analysis technique lets you better prepare for each eventuality and make the most informed choices for each stage of your projects.<\/span><\/p>\n

    There are other benefits as well:<\/span><\/p>\n
