Abstract
It is important that the project gets a good style of communication in order to the success of the project. Therefore it is necessary for members of the project to be able to grasp the situation of the project easily. In the common software project management, it is merely the state of data sharing and it does not consiter that memebers of the project can share the context of the project. In this paper, I study the structure of information sharing to share the context of the project.
