Abstract
We present a review and analysis of the rich body of research on the adoption and diffusion of IT-based innovations by individuals and organizations. Our review analyzes 48 empirical studies on individual and 51 studies on organizational IT adoption published between 1992 and 2003. In total, the sample contains 135 independent variables, eight dependent variables, and 505 relationships between independent and dependent variables. Furthermore, our sample includes both quantitative and qualitative studies. We were able to include qualitative studies because of a unique coding scheme, which can easily be replicated in other reviews. We use this sample to assess predictors, linkages, and biases in individual and organizational IT adoption research. The best predictors of individual IT adoption include Perceived Usefulness, Top Management Support, Computer Experience, Behavioral Intention, and User Support. The best predictors of IT adoption by organizations were Top Management Support, External Pressure, Professionalism of the IS Unit, and External Information Sources. At the level of independent variables, Top Management Support stands as the main linkage between individual and organizational IT adoption. But at an aggregate level, two collections of independent variables were good predictors of both individual and organizational IT adoption. These were innovation characteristics and organizational characteristics. Thus, we can consistently say that generic characteristics of the innovation and characteristics of the organization are strong predictors of IT adoption by both individuals and organizations. Based on an assessment of the predictors, linkages, and known biases, we prescribe 10 areas for further exploration.

Notes
Individual: Research that examines adoption and diffusion of IT-based innovations by individuals.
Organizational: Research that examines adoption and diffusion of IT-based innovations by organizations or organizational units (such as IS Departments).
Since its founding in 1989, this interest group has been at the forefront of innovation diffusion research. DIGIT meets annually as a pre-conference event at ICIS (International Conference in Information Systems) and has consistently attracted the top diffusion researchers and explored the most promising advances in diffusion research.
For clarity and readability, we use the convention of bolding and italicizing Independent Variables and capitalizing DEPENDENT VARIABLES.
The publication years of the 99 studies in the review are: 1992 (9), 1993 (8), 1994 (8), 1995(18), 1996 (12), 1997 (14), 1998 (7), 1999 (3), 2000 (7), 2001 (5), 2002 (5), and 2003 (2).
We use the term ‘significant’ to capture both the statistical meaning of significance (at P<0.05) for quantitative studies as well as the broader definition of ‘indicating importance’ for qualitative studies.
We selected .80 as a cut-off because it is a reasonable indicator of a best predictor. While the specific cut-off could be contested, researchers could easily re-do the analysis with a more lenient or more stringent condition because all the data is in Appendix B.
