Which of the following is a potential shortcoming of using sales force opinions in demand forecasting? D. Members of the sales force can have difficulty distinguishing between what customers would like to do and what they actually will do. Customers themselves may be unclear regarding what they'd like to do versus what they'll actually do. Suppose a four-period weighted average is being used to forecast demand. Weights for the periods are as follows: wt-4 = 0.1, wt-3 = 0.2, wt-2 = 0.3 and wt-1 = 0.4. Demand observed in the previous four periods was as follows: At-4 = 380, At-3 = 410, At-2 = 390, At-1 = 400. What will be the demand forecast for period t? B. 397 The forecast will be (.1 380) + (.2 410) + (.3 390) + (.4 400) = 397
