Supply chains in the business literature

Changes in the structure of 20th century international industrial organisation that have incited research interest among economists have also driven a significant body of work in the business literature. Indeed, many of the factors driving the changing industrial structure are derived from business. Examples include the innovation and implementation of assembly lines, scientific management, modularisation, lean manufacturing, and just-intime production. While the economics literature has produced terminology such as “task trade”, “vertical specialisation”, and “production sharing”, the business literature tends to emphasise “supply chains”. This is in conjunction with terms from political economists and development theorists that include “value chains”, “global commodity chains”, and “global production networks”. Of these, the supply chain provides the most relevant perspective for the business practitioner. Networks of firms are viewed from a focal firm perspective, and the supply chain ontology adopts various dimensions to orient a firm with its network surroundings (for example, direct-extended-ultimate supply chains, horizontal tiers or degrees of separation, and vertical structures within each tier). Further functionalising the supply chain concept is the field of supply chain management (SCM). Born from multidisciplinary roots that include logistics, marketing, management, and sociology, SCM has developed into a distinct field of study over the past fifty years. SCM theory has only recently reached a state of maturation where it produces operationalisable concepts and tools, but progress is being made in advancing both the overarching field of SCM and the specific issues that fall under the SCM umbrella. This chapter will review the overarching field, while Part II and its chapters will address the specific issues.
