Many companies push for faster cycle times and shorter supply chains, driving towards make-to-order production. These trends may appear to reduce the importance of forecasts. However, a closer look into P&G and their business reveals that sales forecasts are still very important and have a far reaching impact stretching from the supply network through to Wall Street. This thesis evaluates the forecasting process in a company like P&G. The thesis delves into the accountability around sales forecasts and proposes a top-down, statistical process for creating and tracking forecast accuracy which was implemented across P&G's global organization. Another analysis is conducted on the evaluation of a new demand planning system which provides more granular input data for generating forecasts, and the implications from this trial on the demand planning process. Finally, an assessment on the efficiency of current systems is also detailed.by Christy A. Prilutski.S.M.M.B.A
