This caselet can be used to facilitate understanding of the concept of Forecasting in Operations Management. Bangalore-based Dstore (P) Ltd. (Dstore) is a growing pen drive manufacturer. The company's founder John Paul (John) faces a typical inventory problem i.e., overstock or shortage of few items because of inaccurate forecasting of demand. Since the inception, John had used the previous month's sales as the base to forecast for the next month and planned production accordingly. Nevertheless, Dstore was continuously facing the problem of overstock or shortage. To avoid this problem, John wanted accurate forecasting and he gave this assignment to the new joinee, Ram Charan (Ram). Ram wanted to do the forecasting as accurately as John expected it to be. Can Ram find a solution to the problem at Dstore? Will he be able to identify an apt method of forecasting suitable for Dstore?
