Two reasons for low success rate of the practical implementation of BPR are the lack of good models and consideration of information system development stage in a BPR project. This paper suggests an Integrated Business Process Model (lBPM), which incorporates two distinct but interrelated points of view: form and business process. By integrating the form model with the business process model, the IBPM has advantages in peforming BPR Projects; it helps to build the model, to analyze and redesign business processes, and to do requirement analysis of information systems. This paper also suggests a new BPR supporting tool, BRAW Ⅱ(Business Reengineering Assistance Work-bench version 2.0). BRAW Ⅱ supports IBPM and manages full stages of BPR project. In the design of BRAW Ⅱ, the linkage between results of a BPR project and requirements for information system developlnent is considered.
