Study On Supporting System And Performance Evaluation Of Business Process Reengineering

As Information Technology becomes a ubiquitous part of an increasingly globalised ecomony, the world's economy is fast transforming from an industrial economy to a knowledge economy and 3Cs (Competition, Customer, change) pose increasingly serious challenges to enterprises. Business Process Reengineering(BPR) has become a very important means both to the development of enterprise and the increase of competitiveness. In China, poor performance of BPR has become a major obstacle to the informatization of enterprises and thus hindering enterprise's development. How to more effectively improve the performance of BPR and promote the success of BPR is one of the urgent problems to be solved in this research field.To explore effective BPR methodology and promote the success of BPR, four BPR projects were analyzed in depth. This thesis identifies three key aspects for BPR: a thorough understanding of the mechanism of impetus and resistance of the enterprise, a good BPR supporting system and a effective method for evaluating of the BPR achievements. Subsequently, this thesis provides thorough analysis for them.Firstly, the composition, sources and mechanisms of impetus and resistance of BPR are investigated. In conjunction with the theory of Mechanical Dynamics, a"dynamic model of BPR"is established by using the principles and methods of systems analysis. The necessarily condition for successful driving the implementing of BPR: the interior impetus should be greater than the interio resistance is proposed through the analysis of the model. This condition could help enterprises to decide whether it is appropriate for implementing BPR, the analysing of the dynamic model is a very important input to decision making of enterprise, it reduces the risk of BPR, and ensures a correct BPR implementation.Secondly, based on analysing the mechanism of impetus and resistance, three main support systems are introduced, including internal environment supporting system, capability supporting system and resource investment supporting system. We, then, proposed a conceptual model of BPR and a hypothesis describing the relationship between the BPR and its supporting systems. Factor Analysis, Correlation Analysis, Multiple Linear Regression, Canonical Correlation Analysis and One-Way ANOVA are as well as the SPSS13.0 statistical software is used to test the hypothesis. The variables of BPR support system are defined; the relationship between BPR support system and BPR is concretely revealed; the relationship between the depth of BPR implementation and the degree of BPR success is studied; it preliminarily explored how contextual factors(for example, the size of the enterprise and who owns the enterprise) influence BPR. The result showed that: (1) The supporting systems played a positive promotional role in success for BPR, and the different supporting factor gives a different contribution in the BPR process; (2) The depth and extent of implementing BPR play a positive role in the success of BPR; (3) There was a significant difference in the depth of implementing BPR among enterprises of different sizes; (4) There was significant difference in capability supporting system, resource investment supporting system and the extent of implementing BPR among enterprises in different ownership. Through theoretical and empirical research, the critical factors are distinguished from support system, and advices for making BPR successful are provided.Finally, taking a systems approach, we established a set of indexes for BPR performance evaluation. A hybrid model called DEA/AHP model was proposed to deal with the evaluation of business process performance. With this method, the DEA was firstly used to develop a pair-wise comparison matrix, and then the AHP applied to evaluate the performance of business process using the pair-wise comparison matrix. Using objective data instead of human subjective judgment for performance evaluation work is the significant advantage of this hybrid model. In the case study, a project of BPR with CJ Hydraulic Machinery Manufacturer was used to demonstrate the effectiveness of the DEA/AHP model.In this work, based on the practice of implementing BPR, we proposed the key steps for successful implementing BPR for enterprises, and then we provided a feasible operational method for each step. With the case study, it showed that the theoritical analysis and conclusions in this work were correct and effective. Therefore, this work could provide a solid theoretical basis and practical guidance for improving the performance of BPR in Chinese enterprises.
