In a constantly changing global competitive environment, an organization's supply chain agility directly impacts its ability to produce, and deliver innovative products to their customers in a timely and cost effective manner. While the beneficial impact of supply chain agility is generally acknowledged, very little research exists to date addressing how an organization can achieve supply chain agility. This study first presents a framework of an organization's supply chain process flexibilities as an important antecedent of its supply chain agility, and then establishes the key factors that determine the flexibility attributes of the three critical processes of the supply chain-procurement/sourcing, manufacturing, and distribution/logistics. Using empirical data, we develop flexibility and agility scales related to our supply chain agility model, and then test the model. Findings reveal that supply chain agility of a firm is directly and positively impacted by the degree of flexibility present in the manufacturing and procurement/sourcing processes of the supply chain; while it is indirectly impacted by the level of flexibility within its distribution/logistics process. The results also support our view that a firm's supply chain agility is impacted by the synergy among the three process flexibilities in its internal supply chain. #

a b s t r a c tIn this study, we examine the structural characteristics of supply networks and investigate the relationship between a firm's supply network accessibility and interconnectedness and its innovation output. We also examine potential moderating effects of absorptive capacity and supply network partner innovativeness on innovation output. We hypothesize that firms will experience greater innovation output from (1) higher levels of supply network accessibility and supply network interconnectedness, (2) the interaction between the levels of these two structural characteristics, (3) the moderating role of absorptive capacity on supply network accessibility and the moderating role of supply network partner innovativeness on supply network interconnectedness. Supply network partner relationships are drawn in the context of the electronics industry using data from multiple sources. We use social network analysis to create measures for each supply network structural characteristic. Using regression techniques to test the relationship between these structural characteristics and firm innovation for a sample of 390 firms, our findings suggest that supply network accessibility has a significant association with a firm's innovation output. The results also indicate that interconnected supply networks strengthen the association between supply network accessibility and innovation output. Moreover, the influence of the two structural characteristics on innovation output can be enhanced by a firm's absorptive capacity and level of supply network partner innovativeness. By addressing the need for deeper structural analysis, this study contributes to supply chain research by accounting for the embedded nature of ties in supply networks, and showing how these structural characteristics influence the knowledge and information flows residing within a firm's supply network.
