Select a service organization (e.g., restaurant), manufacturing organization (e.g., Ford) or retailer (e.g., Home Depot). Explain their mission and overall strategy. Then discuss the role of forecasting in that organization. Explain what they may be forecasting, what methods are most suitable for them, how they should measure accuracy of forecast, and the role the forecasting contributes to customer satisfaction.

Calculate either MAD, MSE, or MAPE for the following hypothetical series of actual and forecast demand of car sales. Year 1: 15000 (F), 14300 (A); Year 2: 15200 (F), 14900 (A); Year 3: 15500 (F), 15800 (A); Year 4: 16400 (F), 16380 (A); Year 5: 16300 (F), 16500 (A), where F is forecast and A is actual demand.
