The purpose of this paper is to facilitate knowledge accumulation and creation concerning IS research by summarizing an extension of the resource-based view and IT value literature. We define several constructs, including, inter-organizational IT resources & capabilities, and IT co-creating rents and illustrate a typology of inter-organizational IT resources and their attributes. Finally, we develop a conceptual model of co-creating IT value that integrates the above constructs. Our analysis provides a blueprint to examine the relational rents impacts of inter-organizational IT and motivates research incorporating the RBV and the extended RBV in the field of IS.
