A decision tree is a type of flowchart you can use to visualize a decision-making process. Decision trees help you map out different courses of action and their potential outcomes. By providing an organized decision-making framework and a systematic approach to exploring all of your options, a decision tree can more easily predict your chances of a successful outcome depending on the path of action you choose.
Decision trees are similar to flowcharts in terms of layout, but they are specifically designed for decision-making, not process and workflow documentation. Decision trees are commonly used in strategic planning, research, risk analysis, and other business functions.
Decision trees rely on many symbols to represent the different parts of the choice and the potential outcomes. Common decision tree symbols include:
|Root node||This top-level node contains information about the ultimate objective or main question you're exploring.|
|Decision node||Contains information about a decision to be made; also referred to as a square leaf node.|
|Chance node||Contains details about a chance event or uncertain outcome; also referred to as a circle leaf node.|
|Alternative branches||These branches indicate a possible outcome, action, or event.|
|Rejected alternative||These are branches that show a possible choice that was not selected. Rather than deleting these rejected branches, it's helpful to leave them to provide context and information about all possible choices.|
|Endpoint node||Indicates the decision tree's conclusion; contains information about the final outcome.|
Decision trees give you a visual framework with which to organize your thoughts surrounding a decision. With this approach, you can systematically explore each available option and all potential outcomes.
Professionals in different industries and roles use decision trees to map out all types of business decisions. Some decision tree example use cases include:
Decision trees are important for data analytics and machine learning—both humans and machines use decision trees to analyze and sort data. In fact, most modern algorithms are based on a type of decision tree. Engineers and computer scientists can use decision trees to design algorithms and understand how algorithms behave.
Decision trees can be a valuable tool for entrepreneurs and business development specialists looking to launch a new product or enter a new market with an existing product. Using market data that you've collected and a series of key questions, you can create a decision tree to help you assess product viability and market opportunities.
Decision trees are a helpful tool for risk management and strategic planning. When you create a decision tree, you end up with a robust tool for evaluating which decision paths have an acceptable level of risk and which are too volatile to pursue. Risk consultants and insurance analysts could use tree diagrams for risk analysis and management.
The decision tree's systematic framework helps finance teams consider all possible outcomes of any given financial decision, leading them to the best option for overall organizational health.
Decision trees help you make decisions by showing you every possible choice and outcome. Some key benefits of decision trees include:
Decision trees provide a visual framework for decision-making. Visual aids are proven to boost memory retention and make it easier to recall important details. When you have a complex issue to analyze or a weighty decision to make, using a visual tool can help streamline the process. Decision trees are easy to make and follow and can help simplify even the most complex issues.
When you take the time to see all sides of an issue and explore all possible outcomes, you're more likely to make a decision that leads to a positive outcome. Decision trees are designed for exactly this purpose—forcing you to slow down and consider the decision from every possible angle.
