In this paper, we study the time dimension of individual decision of IT adoption. Based on literature in technology adoption and social influence, four antecedents are theorized to have impacts on time to adoption of a new IT. Specifically, we examine the effects of two widely researched antecedents (perceived usefulness and ease of use) and two social influence factors (informational and normative influence). To identify the informational influence, we conduct a field experiment to make information signal salient from normative impressions. We assess the impacts using survival analysis. Our findings confirm that individuals are more likely to adopt a new IT early due to informational influence. Meanwhile, the number of adopters from individuals’ close social connections can exert a normative influence. The findings contribute to the IT acceptance literature by extending the outcome variable to time to adoption and probing further into the social influence mechanism by a field experiment.
