Abstract
As business environment has become more competitive, more complicated specifications are required to be developed for the IT system supporting a company. Moreover, IT infrastructure technologies have been more diverse and development term has been shortened. This trend leads to cause "problematic project" so to speak. In this paper, in order to prevent problematic projects from occurring, the plans and effects of PJ-Mart, which is a project visualization tool for grasping the status of many development projects being conducted in parallel, will be proposed.
