Abstract
The effectiveness of the progress management using EVM - Earned Value Management, no longer remains in the level of research or theory, and its recognition is increasing also in the practical area especially among project managers. Since EVM has a characteristic of converting every settlement of work to earned value, i.e. a project or a subsystem, there is a problem that it is difficult to grasp the actual condition of progress only with EVM in the operating process. Although correspondence of using other progress management techniques together as solution can be considered, it cannot be sufficient. In this paper, I will solve the mentioned issue above and propose a method of introducing the view point of critical path into EVM, for heightening the effect of progress management using EVM.
