Business Process Redesign(BPR) projects are considered as a high risk project due to its high management complexity, enterprise-wide impact, and steep project costs. This paper intends to reduce that risk by developing a systematic process redesign method, called Dynamic Proecss Modeling(DPM) method. DPM integrateds the customer-oriented process simulation to promote better understanding of the target process and enable performance simulation of the proposed redesing alteratives proir to actual BPR implementations.
