Abstract
It is proposed that "Community" is one of effective mechanism to increase project manager's competency level. However a definition of Community and an operation of the community are not well organized, thus taking various styles and forms. Effectiveness of the community is not clearly measured because of its difficulty in continuous management of cross-departmental functions. Moreover, it is not clear the skills and motivation which are needed for community members. This paper discusses a type of "Community" formation and its effectiveness from the viewpoint of an organization. It is based on the example of the community currently carried out in the company or the public organization. Furthermore, competency and motivation required in order to activate a community are considered from an individual viewpoint. Based on these considerations, I propose the improvement of business activity of a project and the improvement in capability of a project manager which utilized the community.
