This case is used in Darden's first-year core operations class as part of a module on supply chain management. The Musictoday company provided online retailing services for such clients as the Dave Matthews Band and the Rolling Stones. But the lack of a formal inventory-management process had Musictoday concerned about future stockouts that would result in lost sales. This case covers the basics of safety stock within the context of a periodic review system. It introduces students to the periodic review system and provides them with an opportunity to link the optimal review period with the EOQ concept.
