Abstract
To keep the competitive advantage of an enterprise, Business Process Reengineering (BPR) is the best approach to implement enterprise integration and enterprise transformation. Because BPR affects the organization, culture, and functions within an enterprise and decides its future, many researchers study in this field. However most studies intend to solve particular problems, and lack of a methodology in general. So the decision makers of an enterprise do not know how to do it when they need BPR. They spend a lot of money hiring consultants who are not familiar with the feature of their enterprise to lead the project of BPR, and many of them fail in BPR. In this thesis, we will introduce an integrated approach to implement BPR. It combines the studies in the past to connect modeling, procedure, and enabler of BPR. It uses evaluation techniques, project risk management, and enterprise knowledge engineering to develop the detail steps to implement BPR so that the enterprise decision makers are able to understand the dynamics of internal and external environment. Then they can achieve the strategic goals in the future by BPR. The key points of the thesis are: 1. the construction of strategic model, evaluation model, and process model, 2. the detail steps to implement BPR and risk management, 3.the modules of enterprise resource planning system, 4.the establishment and application of enterprise knowledge base. First, the enterprise decision makers have to understand the content of enterprise knowledge base, including economic environment base, market requirement base, competitive intelligence base, strategic technique base, and process management base. Second, use the knowledge and introduce the strategic model to decide the present position and future position in the enterprise space and search appropriate implementation techniques in methodology space. Then use the evaluation model including the top-down requirement evaluation and bottom-up standardization evaluation to set the detail goals of BPR. Finally choose the key process and information module and construct the As-Is model and To-Be model by process model. Third, implement BPR project through the four stages of detail steps, including project planning stage, process analysis stage, system setup stage, and system running stage. We also study two cases of electronic companies in Taiwan to verify the approach introduced in this thesis. These two companies implemented BPR by introducing enterprise resource planning systems. Moreover, we will give some conclusions and suggestions so that the decision makers are able to lead their enterprise to success through BPR.
