IT diffusion and innovation models: the conceptual domains

This paper describes a qualitative, empirical analysis of a case setting involving diffusion of information technology innovation within and between several commercial organizations. Each of three innovation models is used to develop an analysis and describe what is learned about the case. These three models include the integrated push-pull model, the linked-chain model and the emergent model. Each model leads to distinctly different, but complementary knowledge about the case setting. The analysis and learning from each model are compared and the distinct conceptual domain of each model is circumscribed.
