Abstract
Project Management is required to reach an appropriate decision under difficult condition. One way to make a project successful is an understanding the essence of past experiences. To develop a scheme for learning from the past experiences, it is important to accumulate valuable knowledge of organization and to develop an ability to use the knowledge. We think that ability to use the knowledge consist of ability to use knowledge to find the timing and bility to use its own context to replace the knowledge. A training using the case method is important to develop these abilities. In this paper, we propose the case method which include development of teaching materials and instructional mode. We evaluate the teaching materials and the instructional mode, and show the effectiveness of the case method.
