Much of our prior knowledge of information systems (IS) usage is based on its acceptance or continuance without understanding whether users are likely to use the IS or not. Prior models of IS usage provide a limited understanding of one's intention to use the IS, given that IS usage or continuance does not necessarily suggest the subsequent use of the IS. Even if people use particular IS, there is no guarantee that the users always use the IS. This study proposes an IS usage intention model based on the information asymmetry theory to compliment previous studies that mostly focus on IS usage or continuance without considering the possibility of its use. For IS usage research, this paper proposes one of the earliest usage models of IS. For practitioners, this study provides some guidelines for IS manufacturers on how to derive the most return on their system development efforts with a successfully high usage rate in the market for their newly usage systems.
