Guide to understanding tree diagrams

What is a tree diagram?

A tree diagram allows users to visualize possible outcomes and probabilities for a given situation. Tree diagrams, also called decision trees, are particularly useful in charting the outcomes of dependent events, where if one element changes, it impacts the entire outcome. Tracking and analyzing cause-and-effect scenarios is much easier when you have a visual aid such as a tree diagram.

In a tree diagram, each "branch" of the tree connects an idea or a step in the process to a possible outcome. Outcomes are commonly referred to as "nodes" on a tree diagram. The resulting diagram resembles a tree with many options and outcomes that branch off from the original idea.

Tree diagrams are versatile and useful for decision-making and other tasks across various fields and industries, including marketing, software development, logistics, project management, and more.

Examples of when to use a tree diagram

Tree diagrams are popular for brainstorming, problem-solving, and other idea-generation exercises. For more information about when to use a tree diagram, check out these examples:

Brainstorming possible outcomes of a scenario

Tree diagrams are designed to help you thoroughly explore the possible outcomes of different problems and scenarios. Marketing and UX professionals can use tree diagrams to explore user experience paths and the various possible outcomes along different customer journeys.

Problem-solving and root cause analysis

Tree diagrams are a helpful tool for problem-solving, including troubleshooting and root cause analysis. Software developers can use tree diagrams to analyze coding issues and find fixes during website and app development projects.

Anticipating potential workflow issues

Before you launch a new process, product, or service, you can use a tree diagram to anticipate potential issues along the way. For example, supply chain managers can use tree diagrams to map out resource allocation and plans for a new product launch, exploring various options and identifying potential bottlenecks and roadblocks before beginning the project.

Indicating the hierarchy of tasks

The tree diagram's hierarchical format is useful for project planning, especially when your project involves many different tasks and subtasks. Project managers can use a tree diagram to specify the task hierarchy for a project, helping project participants understand and agree upon each task's order and priority.

Benefits of tree diagrams

Tree diagrams help you explore potential outcomes in an organized, visual way. Some key benefits of tree diagrams include:

Better decision making

Tree diagrams provide a visual framework for decision-making, giving you an organized and systematic way to explore your options. This helps you gather and analyze all the data you need to make the best decision and get the best outcome.

Enhanced troubleshooting

The tree diagram format provides a visual aid for evaluating problems and trying different fixes. When you create a tree diagram for your problem and add a branch for each new idea as you troubleshoot, you're more likely to find a solution quickly and easily.

Streamlined workflows

Tree diagrams make it easy to record and replicate workflows, helping you streamline processes and get your team on the same page about the best way to do certain tasks and projects. With your workflows documented and streamlined, your team will enjoy greater unity, harmony, and productivity.

How to make a tree diagram

Create a tree diagram by following these simple steps:

  1. Choose your main concept, idea, or topic. This could be a problem you need to solve, a project you're starting, or another topic.
  2. Place your main concept at the top of your diagram. Tree diagrams are hierarchical, so you should always start with your biggest, broadest idea and get more specific as you go.
  3. Create the first branches. Your first level of branches will be ideas or steps that would come immediately after or are immediately related to the main concept.
  4. Keep adding branches. Add more ideas based on your first layer of branches and continue branching off until you reach a conclusion or outcome of each path.
  5. Finish your tree diagram. Once you've exhausted all ideas, you should have enough possible outcomes mapped out to assist you in solving your problem, making your decision, pursuing your project, or moving forward with whatever situation inspired your tree diagram.
  6. Make adjustments as needed. If the situation in question changes, you may need to tweak your tree diagram. Typically, the branches in a tree diagram rely heavily on the ideas they connect to — so if one element changes, it will likely have a ripple effect on the rest of the chart.
  7. Share your insights. Distribute your tree diagram or present your insights to team members and stakeholders.
