This study presents the results of an exploratory study of Fortune 1000 firms and their enterprise resource planning (ERP) usage, as well as benefits and changes they have realized from ERP. The study empirically examines ERP in these organizations to provide insight into various aspects that firms can use to evaluate how they are managing their ERP systems. Findings provide information about functionality implemented, extent to which benefits are realized, extent of ERP-related organizational changes firms have realized, and the way firms measure ERP success. The study also addresses the extent to which various types of ERP software have been implemented and whether there is a relationship between type of software and benefits. Finally, it examines ERP-enabled change in light of organizational configuration.
