Rethink of Task-Technology Fit Theory: The Moderation Effect of Individual Characteristics on Technology Evaluation

摘要

Task-Technology Fit (TTF) model has been examined widely on performance impact. However, utilization still cannot be explained accurately by existing literature. In this paper, we examine why TTF sometimes fails to predict utilization accurately through a comprehensive study. In other words, this study tries to provide a rational explanation about why individuals sometimes would not choose the technology with better fit for the tasks. A research model was developed drawing on the existing IS literature. To evaluate the research model empirically, a lab experiment was conducted, and the resulting data has been used to test both measurement and structural model. The paper concludes with theoretical and practical implications.
