In my opinion, the greatest sin of all is that we have spent thirty years developing forecasting processes that are largely not used or trusted by the organizations that they serve. In order, the seven sins of demand planning are:
Sin #1. Not Using the Statistical Forecast to Drive Continuous Improvement
Sin #2. Only Owning Part of the Forecast
Sin #3. Misuse of Downstream Data as an Input
Sin #4. A Project not a Program
Sin #5. Not all Items are Created Equally
Sin #6. Forecast with the End in Mind
Sin #7. Arrogance. Not serving the Organization.
