As recently discussed on this website, the paradigm of SCM research should refer to the system “supply chain” rather than to the system “company” or to the system “supplier-buyer relationship”. In their interesting conceptual note, Supply Networks and Complex Adaptive Systems: Control versus Emergence, Choi et al. (2001) acknowledge the notion of a supply network as a system. The authors go even further and argue that supply networks should be recognized as a complex adaptive system (CAS). Choi et al. propose that many supply networks emerge rather than result from purposeful design by a singular entity. They also emphasize that when managing supply networks, managers must appropriately balance how much to control and how much to let emerge. A similar viewpoint has later been taken by Surana et al. (2005; Supply-chain Networks: A Complex Adaptive Systems Perspective). Can the notion of a supply chain as a complex adaptive system be a building block for the missing paradigm of our discipline?
