Abstract
An information system is usually developed by a group of the engineers whose engineering skill levels are known to the project leader and those unknown. This contains a lot of uncertain factors in the productive power of the project team. In the present severe situations, the project team is expected to attain various kinds of management goals such as reduction of resources consumed by development of information system (cost, man-power, developing environments, etc.), high quality of the system, and shortening of development period etc. The project is expected to attain all those goals when the system is completed. This paper tries to clarify the project management works of grasping and controlling project works for attaining the goals given to the project, and proposes a model for the behavior.
