Review on Vensim by Sean Burnett

I love how easy it was to use, you don't have spend time learning all of its features! It guides me through so much that we need not worry about mistakes or getting confused when using any feature at anytime in our day-to.- The ease with which one can enter their own data into models makes this an ideal tool even if most people are familiar within certain frameworks such as cost analysis etc.-- Greatly reduced project management costs-- More efficient than other tools since less training/learning required (as compared against others).
