Abstract: We propose an integrated model that explains performance impacts of information systems (IS) at the individual level. We incorporate nature of IS use along with task-technology-fit and IS use as determinants of performance impacts of IS at the individual level. Empirically validation of our model indicates that it explains nearly 60% of the variance in performance impacts of IS compared to 16% for the technology-to-performance chain model. These results confirm that the integrated model provides a fuller understanding of performance impacts of IS at individual level by including both task-technology-fit and nature of IS use, an aspect not addressed in the extant IS literature. The theoretical contribution of this research lies in the development of a model for performance impacts of IS that has significantly higher explanatory power than the existing models. We provide managerial implications of our research findings by discussing how to leverage the value of information systems at the individual level.
