Business Process Reengineering (BPR) is defined as the fundamental rethinking and radical redesign of business processes. BPR is also known as a major approach widely used in facilitating Enterprise Resource Planning (ERP) systems implementation. In addition it has been suggested that an awareness of cultural differences is critical to ERP success. In this paper we examine the impact of human and management organizational subsystems on business process change and performance. We use a comparative study of four Chinese organizations with and without ERP systems. The findings of this study prove the importance of soft aspects in business process change through implementation of ERP systems.
