INFORMATION TECHNOLOGY ADOPTION ACROSS T MF: A CROSS-SFCTIONAL COMPARISON OF

The process of information technology adoption and use is critical to deriving the benefits of infor- mation technology. Yet from a conceptual stand- point, few empirical studies have made a distinc- tion 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 techr~ology differ on their determi- nants of behavioral intention, attitude, and sub- jective 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 characteris- tics 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 instru- mentality beliefs of usefulness and perceptions of image enhancements.
