This chapter discusses demand management and outlines several key learning objectives. It focuses on forecasting, the sales and operations planning (S&OP) process, collaborative forecasting approaches, and the fulfillment process. Effective demand management requires coordination between departments and viewing demand information strategically rather than just tactically. The chapter also examines different fulfillment channel options like direct-to-customer, integrated, dedicated, outsourced, drop-shipped, store, and flow-through fulfillment. Each channel has advantages and disadvantages regarding factors like costs, inventory management, and order conflicts.
