The process of information technology adoption and use is critical to deriving the benefits of information technology. Yet from a conceptual standpoint, few empirical studies have made a distinction between individuals' pre-adoption and post-adoption (continued use) beliefs and attitudes. This distinction is crucial in understanding and managing this process over time. The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre-adoption and post-adoption beliefs and attitudes. The examination of Windows technology in a single organization indicates that users and potential adopters of information technology differ on their determinants of behavioral intention, attitude, and subjective norm. Potential adopter intention to adopt is solely determined by normative pressures, whereas user intention is solely determined by attitude. In addition, potential adopters base their attitude on a richer set of innovation characteristics than users. Whereas pre-adoption attitude is based on perceptions of usefulness, ease-of-use, result demonstrability, visibility, and trialability, post-adoption attitude is only based on instrumentality beliefs of usefulness and perceptions of image enhancements.

Information technology adoption across time: a cross-sectional comparison of pre-adoption and post-adoption beliefs

The diffusion of an innovation traditionally has been defined as the process by which that innovation is “communicated through certain channels over time among the members of a social system” (Rogers, 1983, p. 5). As such, the diffusion process consists of four key elements: innovation, communication channels, time, and the social system.

New Product Diffusion Models in Marketing: A Review and Directions for Research:

Reviews indicate that the dominant perspective in the diffusion of innovation literature contains proinnovation biases which suggest that innovations and the diffusion of innovations will benefit adopters. As a result, it is difficult to either address or begin answering the questions: when and how do technically inefficient innovations diffuse? or when and how are technically efficient innovations rejected? This article has two goals: (1) to develop a typology that focuses attention on three less dominant perspectives that can be used to guide research on these questions and (2) to suggest how organizational scientists can develop more encompassing theories of innovation diffusion and rejection by using the theoretical tensions that exist between the dominant perspective and the three perspectives developed in this article. These resolutions are important because they indicate that processes which prompt the adoption of efficient innovations may coexist with processes that prompt the adoption of ineffici...

Managerial Fads and Fashions: The Diffusion and Rejection of Innovations

Economics and Information Theory

The diffusion theory literature offers a fairly well-developed conceptual framework for the study of communications. As developed across a number of disciplines, diffusion applies to the flow of information, ideas, and products; its uniqueness is its focus on interpersonal communication transfer. This paper offers new theoretical propositions to advance consumer diffusion research and to provide a foundation for diffusion modeling.
