The study develops the Extended Process-Wide Information Organism (EPWIO) approach to explore a systematical way of displaying and analyzing the retailer business processes, which involves the flows of information, merchandises, and cash. The study also integrates with concepts of balanced scorecard and strategy map to develop process performance measures. Based on a solid application of the EPWIO approach to the business processes of a retailer in Taiwan, the study shows that the EPWIO approach can not only explore the opportunities for business process reengineering but also provide a management framework for assuring the continuous process improvement and the alignment of business processes with company's strategy.
