Abstract
In this project, the systems configuration of X company which is a major service industry company was performed. It is the features that this project is a large-scale project and that development by R/3 is an inexperienced field for us. Moreover, when advancing a systems configuration project, cooperation with a customer is important and this is the point on project promotion. We analyzed the feature of the project as a risk and assumed that communication management was important. In this project, from a viewpoint of communication management serious consideration, we drew out the communication plan and managed the project smoothly. We thought that communication needs suitable approach by time and we improved the plan directly before operation and coped with it. The point is hand return prevention. Consequently, the risk factor was able to be covered and the project was able to be made successful. In this treatise, I report the example in which we made a success of the large-scale project with the above approach.
