This gradient decision tree example shows you how it works.Īlthough you can certainly make a case for Grandmother Willow’s age-old advice to “let your spirits guide you”, sometimes, a more formalized and calculated approach is necessary. When formed together, these elements loosely resemble a tree, which is where the diagram gets its name. There are typically two types of leaf nodes: square leaf nodes, which indicate another decision to be made, and circle leaf nodes, which indicate a chance event or unknown outcome. The leaf nodes-which are attached at the end of the branches-represent possible outcomes for each action. They are most commonly indicated with an arrow line and often include associated costs, as well as the likelihood to occur. Branches:īranches, which stem from the root, represent different options-or courses of action-that are available when making a particular decision. The top-level node represents the ultimate objective or big decision you’re trying to make. There are a few key sections that help the reader get to the final decision.ĭecision trees typically consist of three different elements: Root Node: Take a look at this decision tree example. In this step-by-step guide, we’ll explain what a decision tree is and how you can visualize your decision-making process effectively using one.ĬREATE A DECISION TREE Click to jump ahead:Ī decision tree is a specific type of flow chart used to visualize the decision-making process by mapping out different courses of action, as well as their potential outcomes. That’s where a decision tree comes in-it’s a handy diagram to improve your decision-making abilities and help prevent undesirable outcomes. If you’ve ever wondered how to examine your decisions in a methodical way that helps you determine potential outcomes, assess various risks and ultimately predict your chances for success, wonder no more.
