Abstract
In open system development projects, which are increasing recently, quality of application architecture significantly affects system's total quality and cost. On the other hand, the number ofexcellent architects is limited. In response to this, our company has established a dedicated section that provides pre-activity supports such as guidelines and know-how for application architecture design and process implementation, and post-activity supports such as pfoject review with an aim to reduce technicalrisks. In this paper, we explain our approach.
