This case study in progress compares two stages of usage of a Course Management System at a private university: before a major functionality upgrade, and after. Here, we report the initial study of usage before the upgrade. It extends current research by taking into account prior use, and noting features (whether in the previous system or not) that attract new implementers. The focus of the study is on Perceived Characteristics of Innovations and management behaviors that facilitate effective implementation of system features. The instrument used by Van Slyke, Lou and Day will be used to study secondary adoption both before and after the upgrade, as described by Gallivan (2001). Results of the first phase of research will be available for presentation at the conference.
