The business process problems can be summarized as process structure defects, lack of supporting mechanisms and lack of supporting system. The business urgency-expected return matrix scoring method, which can effectively sort the importance of the process problems was also analyzed. The implementation method and key elements of process optimization were discussed, and the evaluation index system of process optimization was also constructed. The continuous customer-oriented business process optimization can effectively improve the quality of the process operation and enhance the level of enterprise operation management.展开更多
