  2. Session 1:Previous Research Experience- what is ERP?- what is ERP post-implementation?- what is ERP maintenance?- previous research outcomes

  3. Section 1: Previous research experience What is ERP? • Enterprise resource planning • Characteristics: integrated, cross-functional, modern business application packaged software • Vendor (int’l): SAP (Germany), Oracle (Calf.,USA), PeopleSoft (USA), J.D. Edward (USA) • Vendor (Taiwan): Data Systems Consulting Co., Ltd. (鼎新電腦), Wellan System Co., Ltd. (偉盟系統股份有限公司),Datawin (鉅茂科技股份有限公司). • Market: generate nearly $20B in revenue in year 2002

  4. What is ERP post-implementation? • Activities after system implementation

  5. What is ERP maintenance? • Post-implementation activities • Undertaken by the client-organization • Targeting at • keeping the system running correctly • operating well in a changed environment • providing user-support • realizing more business benefits • maintaining the installed system a supported version SOURCE: Ng, C.S.P., G.G.
