Free Live training (Zoom or Teams, whatever you prefer)

If you need, we will book a live one-hour one-to-one training session for you, demonstrating the various features of this software. We will walk thru the user interface and show you how to model a problem that you are concerned about.

Easy Manipulation of a Decision Tree

Not only can you make a decision tree, but you can also manipulate the tree in any productive way you want. You can cut or copy a subtree and replace a node with the subtree easily. Forgot to add a decision node between 2 nodes? No worries. You can insert a decision node, chance node, or a parallel node quickly from the context menu. Learn More

Perform Sensitivity Analysis

Sensitivity analysis is a crucial part of decision analysis. A decision won't be robust until a sensitivity analysis is performed. Decision Tree Maker & Analyzer software calculates the sensitivity of all variables and display a sorted list based on the degree of sensitivity. Learn More
