According to the definition of "System" in various standards and handbooks, a systemdoes not necessarily have hardware-software components. This means that a social system without hardware-software elements is a kind of system. However, systems engineering techniques are not directly applied to define a solution of a non-technical social system's problems. In this paper, we propose a standard approach to find out multiple view points todescribe architecture, because the view points are one of the most important aspects of architectural design activities. And also we show one example that we applied our proposedapproach to non-technical social system: insurance system. It proved to be positive in applying architectural design technique with appropriate view points to design social system architecture.
