DECENTRALIZED DECISION-MAKING, SUPPLY CHAIN SIMPLIFICATION AND SERVICE INNOVATION: AN INSTITUTIONAL PERSPECTIVE ABSTRACT Multinational organizations have generally focused on centralizing decision-making as a means to increase market efficiency and effectiveness. However, this strategy approach warrants a close examination. Arguably, decentralized decision-making is an important avenue towards integrating partners within a supply chain relationship. Process simplification through decentralized decision-making enforces tight coordination and collaboration and ultimately identification to the network. This phenomenon suggests that the network is the more important environment and the vehicle by which the focal organization achieves its goals of achieving greater probability for efficiency, capability (service innovation) and market success. This paper argues for and empirically tests the concept of decentralization through interorganizational relations by examining the phenomenon through a neoinstitutional lens. Neoinstitutional theory integrated with resource dependence theory help to support the concept of process simplification to achieve isormorphism with the network. The Peopleās Republic of China provided the background to explore centralized and decentralized decision-making structures.
