A multiple-theory analysis of a diffusion of information technology case

Abstract

This paper describes a multiple-theory analysis of a diffusion of information technology case. Three innovation diffusion models, the interactive model, the linked-chain model and the emergent model, are used to develop an analysis that describes the essential knowledge that each model produces. Rather than develop conflicting stories, each model leads to distinctly different, but complementary, knowledge about the case setting. More generally, the analysis enables us to circumscribe the distinct conceptual domain of each model. These domains define the scope of research questions that can be addressed by each of the innovation diffusion models. In addition to the theoretical implications, the paper also describes the practical indications and actions of the case subjects.
