Introducing Guesstimate, a Spreadsheet for Things That Aren’t Certain
Ozzie Gooen

This could be very useful for financial modeling by investment bankers and corporate development departments evaluating potential acquisitions. They create base case, best case and worst case models with different “reasonable assumptions” using Excel. Excel creates a false sense that you are accurately forecasting three different future states if you just have your assumptions right for each future state. This should help management teams internalize that revenue and expense forecasts are guesstimates rather than accurate statements of what will happen under a few scenarios.
