Study On The Methods Of Business Processes Analysis And Re-engineering Evaluation

Business Process Re-engineering(BPR)is an important issue in the modern enterprises. Because of integration of the world economy, the diversification of buyer's requirements and science and technology improvement, the business environment and management environment of companies have been deeply changed, and the traditional management pattern has been austerely challenged. Only initialing innovation can the company survive and develop. So BPR has received much attention because of it's ideas of innovating, focusing on customers and reengineering processes.This dissertation deeply explores the analysis and evaluation of business process in BPR with the ideas and methodology of Activity Based Cost, Queuing Theory, and Gray Theory. Aim at reduceing risk of BPR, the key problems are the analysis and evaluation on the business processes in existence and the to-be business processes. Although BPR is extremely advanced management theory, its successed rate is low in practice. The main reason is short of a reasonable and quantitative evaluation index system. It also lacks of effective ways to evaluate reengineering scheme. Based on studying the present situation of corporation's performance evaluation index system, busines process evaluation index system, the ways of business process cost calculation and analysis, business process efficiency analysis, and the ways to evaluate reengineering scheme studying by scientists. This dissertation proposes that it is effective way to set up a sort of perfect business process evaluation index system and find a perfect ways to evaluate reengineering scheme.On the base of analyzing and studying business process's structure and feature, this dissertation studies the definitions of BPR, and gives an formal description of business process and the model of BPR effective graph. Because the cost of BPR is high, corporation must focus on core business processes. Macroscopic and microcosmic fact effects BPR on four aspects, they are the great change of business environment, the development of information technical, the weakness of new management theory, and the requesting of new management technology. This dissertation sets up an influence model on BPR.On the base of analyzing performance of business processes sufficiently, this dissertation proposes a macroscopic evaluation index system that reflects business process's all aspect, it's business process cost, business process quality, business process customer satisfaction, and business process efficiency, puts forward the way how to getting the sub-index. About business process cost analyzing, through using Activity-Based Costing (ABC) and Activity-Based Costing Management (ABCM) theory, this dissertation proposes a new way to classify business process cost character. The business process cost is classified as three kinds of type, such as process variable cost, long variable cost, and fixed cost. On the base of setting up universal cost characteristic model, by way of satisfying business process cost analyzing, this dissertation subdivides the univerals cost characteristic model on two grades. Through subdividing, the models can provide dynamic and accurate business process cost information. On the basis of relationship of four indexes, this dissertation predigests the concept of business process quality and proposes business process quality "coincident" criterion. Through comparing process product/service quality with "coincident" criterion, business process quality can be measurable by quantity. This dissertation gives a method to analyze business process customer satisfaction based on backward position customer evaluation, and sets up a model for calculating business process customer satisfaction.Business process efficiency is analyzed in the dissertation. First, business process time model is set up that reflects all aspect of business process. Afterward, on the principle of simplification complex time problems, a complex business process' queuing model is established by using queuing theory. The mo...
