20 Business Process Reengineering Principles Organize around outcomes,not around tasks Have those who use the output of a process actually perform the process Treat geographically dispersed units as if they were centralized Link parallel activities during the process,rather than at the end of the process Capture information once at the source

21 Business Process Reengineering Procedures Develop business vision and process objectives Identify processes to be engineered Understand and measure existing processes Identify IT levers Design and build a prototype of the process BPR Examples IBM Customer Credit Company HP Procurement Kodak Camera Production
