Given that resistance to change is a pervasive barrier to Information System implementation, organizations must appreciate the difficult process of Enterprise Resource Planning (ERP) system implementation and the crucial knowledge in change management as well as the complex adoption process in order to derive the benefits of the costly ERP systems. Research indicated most implementation failures involve organizational- and people- related issues. Thus, understanding why people accept or reject information technology is one of the most challenging issues in information systems research. This book provides valuable information in critical success factors and change management strategies for ERP system implementation as well as discussions on three adoption models. This research should help shed some light in the relationship between an information system implementation and the influence of planned change efforts to help people with technology adoption. This book should be useful to professionals in the information systems research and the technology adoption fields, or anyone who may be implementing new technology in their organization.
