To fully examine this definition and model, the role of individual business functions, and how
they are coordinated across functions and across companies, should be examined. Inter-functional
coordination includes an examination of the roles of trust, commitment, risk, and dependence on the
viability of internal functional sharing and coordination. Inter-corporate coordination includes
functional shifting within the supply chain, the role of various types of third party providers, how
relationships between companies should be managed, and the viability of different supply chain
structures. Finally, how all these phenomena vary in different global settings is relevant and, thus,
represented in Figure 3.
