In Operations Rules, David Simchi-Levi identifies the crucial element in a company¿s success: the link between the value it provides its customers and its operations strategies. And he offers a set of scientifically and empirically based rules that management can follow to achieve a quantum leap in operations performance. Flexibility, says Simchi-Levi, is the single most important capability that allows firms to innovate in their operations and supply chain strategies. Simchi-Levi¿s rules¿regarding such issues as channels, price, product characteristics, value-added service, procurement strategy, and information technology¿transform operations and supply chain management from an undertaking based on gut feeling and anecdotes to a science.
