This software has been extensively used to teach Decision Analysis at Stanford University. It has also been used by many to solve trees in Excel for professional projects.
This software is a toy. It is not for adults. I wish the makers would be more honest about it up front. DOn't beleive the positive reivews. it works like this: you load it, run it & then are presented with a menu saying 5 options. option 1 is yes/no, it then answers you randomly, yes or no! option 2 asked how many options you are faced with & you enter them all (but it htne picks one at RANDOM) option 3 defer for later or something opton 4 is contact us option 5 is 'about us' Its just a kids toy, not a decision maker
