Examining the interrelationships between supply chain integration scope and supply chain management efforts

In this article, we study the concept of supply chain integration scope by comparing firms that involve immediate supply chain partners in their strategic efforts (narrow supply chain scope) versus firms that involve supply chain partners beyond the immediate level, for example second tier suppliers and end customers (broad supply chain scope). By relying on Coordination Theory and expanding upon Frohlich and Westbrook's ( 2001 ) 'arcs of integration' principle, we propose that supply chain integration scope and the type of supply chain management efforts deployed by firms are correlated. We use data from a large sample of US and European firms to explore the association between supply chain integration scope and supply chain management efforts. The results show that supply chain integration scope can be predicted by a firm's supply chain management efforts. The implications of our results for practising managers are also offered. Our results suggest that supply chain managers should consider the practices identified in this study while deciding on the appropriate level of supply chain integration scope, i.e., which extended supply chain members to include in their strategic planning efforts.
