Electronic linkages between organizations are an important aspect of modern day supply chains. Organizations implement disparate information / communication systems to integrate their suppliers and customers in a supply chain. Though the underlying technologies and protocols of such information systems may differ, they do possess a common characteristic: they all span boundaries of the supply chain partners. Collectively labeling such systems as supply chain management information systems (SCM-IS), we examine a variety of information systems that support the activities in a supply chain. Specifically, we examine two distinct phenomena related to these information systems: the intention to adopt SCM-IS and the adoption of SCM-IS. Using empirical findings from prior literature, we conduct a meta-analysis to understand the antecedents of the intention to adopt SCM-IS and the adoption of SCM-IS.
