Abstract
In order to lead the success of a project, it is important that the project problems are detected and solved early. In order to detect the project problems early, monitoring information updated constantly is helpful. As such information, we can use correspondence stored automatically in a communication system which has functions to communicate among developers. In this paper, we focus on correspondence among developers, and we show that we can detect several problems in a development project easily by monitoring and watching the situation of correspondence among developers. Appling this method for software development is useful. Because in software development, actions by problems in a project strongly show up on communication among software developers.
