Abstract
This paper describes the indispensable requirements for implementing the CCPM (Critical Chain Project Management) by applying the Thinking Process. In recent years, businesses become severe and three commitments of "Delivery", "Quality" and "Cost" become to be important factors more than before. Therefore, we need to introduce high quality management methods into projects. The CCPM is regarded as a high-quality project management method in Europe, the U.S.A. and so on now. The method is researched and applied in Japan, but there are few reports.
