Exceptions are the events or situations that prevent business processes from completing normally. When exceptions such as cancellation of customer order occur, additional time and resources are often needed to resolve them. It is important for enterprise to pay attention to exception; for reducing exceptions efficiently and effectively may trace business process oriented improvement or innovation. In this study, a conceptual level pattern for reducing exceptions is proposed and discussed. In this study, authors conduct a case study in a certain small and medium Japanese company. This study contributes not only to those who work upon business process re-designs in the practice but also to those who research business process management in the academic fields.
