Several shortcomings of traditional diffusion research create major impediments to our understanding of the diffusion of innovations as well as to the development of effective strategies of policy intervention to facilitate diffusion. Among the criticisms of diffusion research are the selection bias of many diffusion studies and the futility of curve fitting as an adequate test of theoretical relevance. These shortcomings can be avoided by substantive and methodological changes in diffusion research. We argue that innovation attributes, together with policies associated with the diffusion of an innovation, account for significant differences in diffusion patterns. An empirical analysis of this thesis focuses on the diffusion of computer applications software in local government. This paper is part of a research project entitled "Diffusion and Adoption of Computer Applications Software in Local Governments."
