About the App

We created TreeDecisions to provide a simple and easy software for professionals seeking to make decision trees. It accomplishes the basics, enabling users to build a tree structure that reflects a decision and the possible but uncertain paths that might follow. A user can enter estimated probabilities, and estimated outcomes and estimated costs of achieving those outcomes. Based on the numerical values entered, the software will calculate an overall expected value, the expected value at each juncture along the way, and the overall probability of each possible outcome.
