Most of the software packages require a decision to be made at the beginning of the implementation between weekly or monthly forecasting. Rather than force you into a mold, RockySoft chose to develop on-the-fly flexibility to view and analyze both approaches. This allows the customer to better benefit from both their relative merits. Why force a decision that cannot be reversed? Why not let people dynamically switch between methods to gain insight into the products behavior? This ability to dynamically switch among forecast period frequency is a lot like zooming into a stock market graph: Are you looking for close in volatility or long term trend? What can you see up close that was not evident from a wider view?
