System use is a focal concept in information systems (IS) research in light of the fact that the benefits of information systems can only be realized when people use them after adoption. In the past decade, IS researchers have attempted to enhance the conceptualizations of system use from various perspectives. Nevertheless, our understanding of post-adoptive system use still remains at the early stage and scattered. In this research, we attempt to develop an initial post-adoptive model (PAM) based on early and preliminary steps toward a meta-analysis of the system use literature in the top IS journals. These initial steps give us a starting point for a full meta-analysis of this stream of research. Moving forward, we will conduct this analysis so as to develop a picture about the status quo of existing research on post-adoptive system use. Ultimately, our goals are to begin a synthesis of existing research models and point out directions for future research in the area of post-adoptive system use.
