Decision-making might be a complicated process, but free decision tree templates can make the job easier for you.

In any business organization, decision-making involves considering multiple related factors before opting for the right option. Using a decision tree can make the procedure seamless and help organizations easily make tough choices.

This article will offer you a complete guide on the decision tree and discuss its importance, component, use cases, and decision tree-making process. Also, we will share some free decision tree templates with you.

What Is a Discussion Tree?

A decision tree is a type of flowchart that you can use to go through all possible decisions and their outcomes. Every branch of a decision tree refers to a choice you can go for. The good thing about the decision tree is you can scale it up as you wish based on the cause and effect. All you have to do is to extend a branch when a result leads to another course of action. 

Importance of a Decision Tree

Those involved in any type of professional decision-making would know that it is a complicated process. To come up with a decision, you need to have a deep understanding of facts and intuition. 

People often use tools like a decision tree template to outline all possible outcomes. It also helps you visualize the necessary steps for arriving at the best decision.

Decision-making is a kind of problem-solving that needs you to apply logic and probability. Using a decision tree template, users can readily organize all the data available. They can also fill the gaps by combining probabilities with the information to make the right decision.

Startups and SMBs will find decision trees particularly helpful because these companies have limited resources, and it is not easy to get financial buy-in. On the other hand, large companies and enterprises can utilize decision trees to find the right options before presenting them to their stakeholders or an internal team. 

You can use decision trees to find out if a new product is viable or if a product can get investments. All you need is to utilize your creativity to evaluate the endless options. 

Common Components of an Ideal Decision Tree

Though decision trees help you deal with complex data, these are not difficult flowcharts to understand. The followings are the essential components you will find in all decision trees.

• Root Node: Every decision tree starts with a central theme or question. It is called the root of a decision tree. All other nodes and branches come out of it.

• Leaf Node: These nodes represent various decisions and outcomes. It could be a decision node (square shape) that represents a decision, a chance node (circle shape) that represents the probability, and an end node (triangle shape) that represents the result or outcome.

• Branch: These are used to connect different nodes. 

Here are some additional terminologies often used in a decision tree:

• Internal Node: Every node between the root and leaf nodes (decisions and chance nodes) is called an internal node; you can have any number of internal nodes. 

• Pruning: Pruning is the method you use to remove nodes containing irrelevant data when the decision trees become complex. 

• Splitting: When a node gets divided into two or more sub-nodes, we call it splitting or branching. These sub-nodes can be internal or end nodes.

Step-by-Step Guide to Create a Decision Tree

When you are about to create a decision tree, these are the steps you should follow consequently.

1. Have the Central Question: To create a decision tree, you should start by putting your main question in the decision tree template.

2. Add Branches Around the Question: Think of some possible options that you can choose. For each of these, draw a line with a node at the beginning and a leaf node at the end.

3. Include Leaves: Use an if/then statement to label each leaf node. Thus you can point out the consequence of each choice. 

4. Put More Branches If Needed: Keep growing the tree with more branches and leaves with proper labeling. 

5. Evaluate and Decide: As you go on to answer all the questions of the decision tree, you can reach your decision.

6. Check With the Stakeholders: If you have come up with a decision alone using this decision tree template, share the result with the other involved parties before proceeding with your decision.
