Examining Post Adoption Usage: Conceptual Development and Empirical Assessment

Understanding post adoption behavior has emerged as an important issue in IS research. Organizations have invested in a plethora of information systems (IS) and enriching the usage of these systems can provide organizations with immense benefits. Prior research has examined factors that lead to continued usage of IS, which is critical. But comprehending usage behavior in the context of effectively using the installed system has not received much attention. This study proposes post adoption usage as a broader concept constituting feature level usage of IS, integration of IS in the work system, and exploration of new uses of IS. To validate the post adoption usage constructs, data (N = 1032) was collected in the context of a web based Student Information System used by students to manage their academic work. The newly developed conceptual structure and measures for post adoption usage exhibit strong psychometric properties. Implications are drawn for future
