About PrecisionTree

Welcome to PrecisionTree, the decision analysis add-in to Microsoft Excel. Now you can do something you have never been able to do before: define a decision tree or influence diagram directly in your spreadsheet. PrecisionTree allows you to run a complete decision analysis without leaving the program where your data is—your spreadsheet.

PrecisionTree helps address complex, sequential decisions by visually mapping out, organizing, and analyzing decisions using decision trees – right in Microsoft Excel. Decision trees are quantitative diagrams with nodes and branches representing different possible decision paths and chance events. This helps you identify and calculate the value of all possible alternatives, so you can choose the best option with confidence.
