I like how easy it is to use, especially when creating calculations for our financial reports in excel! Also very user friendly!! The product has had some updates recently that have made things easier (such as making graphs more intuitive).
There are other programs out there with similar features but we chose this one because of its ease-of -use and ability to create models quickly without needing any programming knowledge or experience. We can easily build complex decision trees using treeage pro healthcare which helps us make decisions about risk management issues at work.
