Abstract
This paper proposes a new simultaneous business design method that is called the global relations diagram of function and demarcation (G-RD). When enterprises aim to perform BPR, they need to design not only business functions but also the relations between businesses. Generally, BPR projects focus on the business functions, and the relations between businesses are not fully designed in many cases. In order to solve this problem, the modeling approach is needed which details not only the business functions but also the relations between businesses simultaneously. This paper introduces the cases where this simultaneous business design method was applied to the BPR projects and the effectiveness of this method utilizing G-RD is evaluated.
