How to Make Decision Tree Diagrams for Process Documentation

Making confident, well-informed decisions is essential for success in any field, whether you’re managing complex business operations, tackling IT service challenges, or designing machine learning algorithms.  

A decision tree can help you accomplish this. It’s more than just a diagram; it’s a powerful tool that organizes choices, visualizes possible outcomes, and ensures consistency in your processes. Think of it as a structured roadmap that simplifies even the most intricate decisions, empowering teams to act with precision and confidence. 

This blog will explore the value of decision trees in business, IT, and more, and guide you through the steps you’ll need to create your own.  

Decision trees can be considered a type of flowchart because both kinds of diagrams are for visualizing processes, but decision trees exist for a more specific use case. 

While flowcharts describe the tasks involved in a process, which could include multiple decisions along the way, decision trees are for a single decision or classification. They are made up only of conditions that guide the viewer through that decision. 

So, while you could certainly refer to your decision tree as a flowchart, not all flowcharts are decision trees. 

Decision tree analysis allows you to visually map out possible outcomes and guides you toward the choice that makes the most sense for your circumstances.  

This is done by building a decision tree: a framework that allows businesses or organizations to make consistent choices or classifications of data. 

Decision trees are helpful for repeated processes that may not be carried out by the same person every time—for example, a task that is shared by multiple team members. The decision tree makes it easy for anyone to understand the process at a glance and ensures that the task gets completed the same way every time, no matter who is doing it. 

Decision Tree Templates & Examples

In IT service management, decision trees can be a helpful resource for incident management. For example, a decision tree can help a newly hired service desk agent execute the correct process to quickly resolve a ticket reported as a possible network security breach. 

With a resource like a decision tree built into the ITSM team’s knowledge base integrated with Jira Service Management, any team member of any experience level can confidently resolve issues and provide excellent service. 

Step 1: The Situation 

First, draw in a square or rectangle to represent the initial decision you’re making. This is called the root node. Give it a label that describes your challenge or problem.  

Step 2: The Branches 

Starting from the initial decision, go through the flow of the decision-making process and include a guide for what the viewer should do at each point where a decision might change the outcome. 

Once you’ve laid out your decision and all the branching scenarios showing what could possibly happen, you’ll use the connector tool to draw lines between them and show the flow of activity. 

Step 3: The Context 

In Gliffy, you can add labels and notes to lines simply by clicking on them and starting to type. Depending on the use case for your diagram, these notes could by your estimated probability of this outcome occurring, simple descriptions like “yes” or “no” to help guide users through the decision tree, or the costs associated with the outcome.
