Abstract
In IAP2M, the perspective about the concept of the management risk with the hierarchy is definitely defined in P2M Version 2.0. Its basic interpretation is to understand the risk not in a way of an obstacle for evasion and exclusion when an organization promotes its project activity, but in a way of on opportunity to learn toward the outside environment. In the main subject, the figure, that the recognition of the risk raises an expanse of an organization and a company toward the outside and gradually changes into the activity of contribution and responsibility to the society, must be seen. In the consideration, the survivable system and system methodology was investigated from the viewpoint of a scientific principle, and the PM activity which is played in the business world was investigated form of the decision-making human being thought. Treat the model which is lead from the investigation above as a compound organization type model, I would like to propose the possibility of the development for maintenance and expansion of the social infrastructure.
