Technology-driven changes have enhanced business efficiency at all levels. In this research, we examine how supply chain (SC) member relationships and e-business adaptation gap among SC partners affect SC performance. Through an empirical study, we found that variation in both information technology (IT) systems (hardware and software) and management's willingness to employ Internet technology play an important role in a firm's e-business implementation. We also found that interdependency and degree of trust among SC members are the major factors that characterize the SC members' relationships. Through ”right” e-business application and management, firms can form an effectively integrated SC that increase market share by being flexible, swift, dependable, and cost efficient.
