INTRODUCTION A supply chain consists of many organizations acting together, with each organization dependent on the performance of other organizations in the chain. Coordination within a supply chain is a strategic response to the challenges that arise from these dependencies. A coordination mechanism is a set of methods used to manage interdependence between organizations. By definition, there are a number of different people, entities, and processes that interact in order to execute supply chain objectives. Coordination mechanisms, then, provide tools for effectively managing these interactions.
