Abstract
Owing to the rapid changes of markets’ demand, the dramatic shortening of the product life cycle, and the stresses of global competition, enterprises devote to the introduction of Enterprise Resource Planning (ERP) system in order to be more competitive. The implementation of an ERP system usually starts with business process analysis. By doing this, the system requirement is clarified first. Practical system design is then progressed to generate a satisfying ERP system. Business process analysis can be conducted through the help of some useful tools. Among these, ARIS-Toolset is widely adopted by enterprises because it provides many graphs and entities to describe the enterprise process. For system design, the Unified Modeling Language (UML) has become a standard tool because it provides many graphic methods to describe the system. UML is an object-oriented language, which not only uses various modeling tools to construct the system components at different stages of system development life cycle, but also generates the corresponsive programs of the constructed system. This research intends to develop an integrated system which incorporates Business Process Reengineering (BPR) concept and ERP implementation methodology. Development of this system is composed of the following four stages. 1. Processes analysis and reengineering: By analyzing and rationalizing the enterprise processes, the optimal business processes can be generated. 2. System demands analysis: From the process analysis, the system requirement should be identified by understanding the relationships between human and system. 3. System design: The system framework is constructed by the static and dynamic analysis of business processes. 4. System coding: By applying UML, system developers can generate the required computer programs from the system framework to finish the design of an ERP system. To evaluate the feasibility of the proposed methodology, this research collects the experience from the reference models provided by SAP and ARIS-Toolset. The construction of material management function for car-component manufacturers was selected for system verification. It is believed that this approach helps the implementation of an ERP system, which can conform to the concept of business process reengineering.
