While most ofthe body ofknowledge associated with calculating EOQs, fair-shares inventory deployment, productivity curves, and other operations management techniques had long been solidly established, new thinking about distribution management had taken a definite back-seat to the then dominant interest inLeanthinking, quality management, and business process reengineering and their impact on manufacturing and service organizations. For the most part, discussion relating to the distri bution function centered on a fairly recent concept called Logistics Manage ment. But, despite talk ofhow logistics could be used to integrate internal and external business functions and even be considered a source of com petitive advantage on its own, most of the focus remained on how companies could utilize operations management techniques to optimize the traditional day-to-day shipping and receiving functions in order to achieve cost contain ment and customer fulfillment objectives. In the end, distribution manage ment was, for the most part, still considered a dreary science, concerned with expediting and thetedious calculus oftransportation rates andcosttrade-offs. Today, the science ofdistribution has become perhaps one of the most im portant and exciting disciplines in the management ofbusiness. In the space of a decade or so the management of supply and distribution channels has catapulted to world-wide prominence as the central fulcrum in the search for competitive advantage. Since the early 1990s, a host of critical trends, events, and ideas have intervened that have dramatically altered the theory and practice oflogistics management and opened fresh areas for research and practicalapplication. Much ofthedialogue isthe result ofthe maturation ofa number of radically new marketplace dynamics such as the growth in power of the "voice ofthe customer," demands for the mass customization of prod ucts and services, a veritable explosion in globalization and outsourcing, a heavy focus on reengineering, cost control, and cash conservation, the end of the vertically integrated enterprise, and several order-of-magnitude break throughs in information and communications technologies. But of allthe dy namics impacting today's business environment, perhaps the two most im- xii PREFACE portant are the rise ofthe concept ofSupply Chain Management (SCM) and the birthofthe Internet. In 1992 SCM and the Internet were not even on the radar screen oflogis tics practitioners and theorists. Simply put, the Internet did not exist and was totally in the realm of odd pockets of"computer geeks" and very academic scientists. As for SCM, while a few visionaries began talking about it as early as 1990, it was really not until the middle ofthe decade that the concept began to gain traction as a new management science evolving out of the logistics concept. Today, SCM and the Internet have come to dominate all thinkingand it has become hard to talk about one without reference to the other. The literature on the topic has grown astronomically. Literally hundreds of articles and books have generated countless pages ofperspectives on SCM/Internettheory and practiceoverthe last few years. The discipline has its ownjournal -Sup ply Chain Management Review (founded 1996) - and trade magazines with evocativetitles, such as e-Supply Chain Management, Supply Chain Technol ogy News, and others, continue to emerge. College courses and business seminars discussingjust about every aspect ofchannel management abound. Most consulting firms have whole practice areas devoted to SCM. The con cept has actuallyengendereda whole genus ofcomputersoftware. The rise to dominance ofthe convergence ofSCM and the Internet has not happened by chance. It has evolved as a response to the very real require ments that companies must now act through theirsupply chains ifthey expect to be capable ofproviding the market-winning value demanded by the cus tomer; they must be agile and scalableto bringnew products to market faster, flexible in the design ofproduction and distributionprocesses, and capable of quick supply channel redesign; and they must be capable ofengineering daz zlingly fast flow order-to-delivery cycles utilizing Internet technologies that eliminate channel costs and redundancies while increasing customer con venience. While the rise and fall ofthe Internet economygave witness to the relative immaturity ofthe dot-com e-business revolution, the dramatics were an unfortunate side-show to the slow, but real changes being engineered by savvy executives who were coming to understand that the emerging ver nacular ofidioms like connectivity, interoperability, networking, e-business, and collaboration were more thanjust the newest management buzzwordsbut were, in reality, the kernels ofnew paradigms ofhow business in the twenty first centurywouldbe conducted. The changes to the concept and practice of distribution management brought about by the SCM/Internet manifold (termed e-SCMin the pages to follow) is the main driver forthe redraftingofthis text. While the word "sup ply chain management" appeared in the original 1996 edition, it was given scant attention. In its place, the concept ofIntegrated Enterprise Manage-
