How to make a decision tree diagram
Start the tree
Drag a rectangle shape onto the canvas near the left margin and enter the main idea or question that requires a decision.
Add nodes as outcomes
Use a circle shape to add nodes that display the name of each uncertain outcome. Add as many possibilities as you want with a minimum of two.
Draw lines as outcomes with estimated worth
Connect your main idea to primary nodes and to the nodes thereafter using lines. To these lines, you can add specific values and estimates of how much impact a particular outcome can cause.
Complete the decision tree and calculate the value
Once every question is connected to a chance event, insert a triangle at the end of the diagram to signify an outcome. Estimate the probability of each outcome and use the nodes and branch values to calculate final values.
Verify and use it or publish and share
Use real-time collaboration to get feedback from your team, or publish the diagram using Lucidchart’s easy sharing options.
