This study examines the effects of cognitive and social factors on system utilization and performance outcomes. The literature has paid considerable attention to social influence as a determinant of individual behavior. We combine the concept of task-technology fit with concepts from adaptive structuration theory to elucidate social influence. In our model, we propose that support from a proper social construction in addition to task-technology fit leads in performance improvement in individuals. Empirical data from 317 individuals across 43 teams in ten companies are used to assess the theoretical model. Our theoretical model is supported by the data.
