What is a decision tree used for?

Decision trees are used to compare options and their consequences, document troubleshooting or approval flows, and explain rules as a series of questions. In analytics they are also used to model probabilities and expected values.

What is the difference between a decision tree and a flowchart?

A flowchart describes the steps of a process in order. A decision tree focuses on a choice and the outcome of each option. Many diagrams mix both; this template is designed for comparing outcomes.

Decision Tree Mind Map Template

By RP Hobbyist · Updated October 2026

A decision tree lays out a choice as a branching diagram: a decision at the root, the options or yes/no answers as branches, and the resulting outcomes at the ends. Seeing every path at once makes it easier to compare consequences, spot missing options and explain your reasoning to others.

This template starts with one decision, a Yes and a No branch, and two outcomes under each. Extend it with further questions, add costs, probabilities or notes to each outcome, and use colors to highlight the path you choose.

When to use a Decision Tree

Choosing between options with different consequences
Documenting troubleshooting steps or support scripts
Explaining a policy or eligibility rule as a series of questions
Comparing risks and payoffs before a business or project decision

What goes in each branch

Decision?: The question to answer, written so it has clear answers (yes/no or a set of options).
Yes / No: Each branch is one answer or option. Add more branches if there are more than two choices.
Outcome A to D: The result of following that path. Add details such as cost, time, risk or probability as child nodes.

Example: Should we build a feature in-house?

Yes, Outcome A: full control, but 8 weeks of developer time
Yes, Outcome B: the mobile release is delayed
No, Outcome C: buy a plugin for $300 a year
No, Outcome D: limited customization, but available this week

Tips

Keep each question to a single decision so every branch is unambiguous.
Put numbers on outcomes (cost, time, probability) where you can; they make branches comparable.
Prune branches that are clearly unacceptable to keep the tree readable.
Highlight the chosen path in a strong color before you export it for stakeholders.
