Abstract
This paper proposes a management method of project containing unpredictable tasks based on CCPM (Critical Chain Project Management). CCPM is known as a project management method to deal with the project buffer delay. However, CCPM is difficult to handle unpredictable tasks because it presupposes the case a clear task to some extent. We classify project tasks by difficulty of the estimation. We can manage the predictable task by CCPM and can handle the unpredictable task by project buffer of CCPM. Further, this paper shows a case study of software requirement specification development based on the proposed method.
