Successful ERP Implementation Model : Exploratory Model from Ernst & Young PER (Package Enabled Reengineering) and Change Management Methodology

성공적 ERP구축 모델 : Ernst & Young의 PER(Package Enabled Reengineering) 방법론과 변화관리 방법론을 중심으로 한 탐색적 모델

According to the Gartner Group, the market for ERP software in Korea is growing rapidly. However, the number of successful ERP implementations is quite few. Standard(unmodified) ERP's are built based on best practices. Improvements expected from successful implementation are based on best practices built into the software. Many improvements are lost through modification to "standard" software. Even minor changes in software can significantly reduce benefits. Both implementation time and risk factors are increased with modifications. We introduce a methodology, called package Enable Re-engineering (PER) and the main components of change management program by Ernst & Young. "To-Be" model could be developed through the software capabilities. And change management processes such as continuous education and self-developments are required. The philosophy of the change management processes is to let the software package drive the re-engineering practices and avoid moving the software toward the "As-IS" process. Extensive top management involvement, major focus on speed, extensive communication program, and "clear" picture of the future are essential components of change management. We are sure that the complied experiences and model have implications for practice and for academicians for their endeavors in their fields.
