Abstract |
This study is divided the activities of the respective projects into the levels closest to the WBS and redrew up process control charts by assigning the cost resources of itemized statement to each work. This was compared with the process charts of existing cases and its deviation was analyzed to derive appropriate dividing criteria of activities. The results derived in this study are as follows: In the case of the existing planned process charts, because the itemized statement system and the WBS are different, the cost and schedule are not interconnected, causing a lot of problems. Because activities in planned processes are not subdivided, adequate progress is not given to actually-performed works and due to that, progress took place on over-achievement, causing problems such as under-achievement of progress and schedule delay. As a result of having applied the method of subdividing the activities as describe above, the “plan vs. schedule” achievement rate increased and the absolute deviation to the unachieved rate and over-achieved rate decreased. It is therefore judged that the application of the EVMS by the subdivision method of activities proposed in this study would be appropriate. |
