Numerous studies have assessed the relationship between information technology (IT) usage and individual performance. However, the empirical evidence on the subject is mixed and contradictory. This paper argues that the current state of empirical research is due to a failure to understand the interplay between IT usage and performance. It argues that the relationship between IT and performance materializes through an appropriation process resulting in two fits: a fit between IT and the task and one between IT and the user. The main premise of this paper is that IT leads to enhanced performance only when this double fit exists.
