Abstract
Based on the investigation of the project failures experienced in NEC, it has been found that most of the cause has been induced during high level study and/or design phase at the early stage of the project, or even the time before the project start. In these cases,it is very difficult to cope with the problems with in the single project. In this paper, authers consider that OPM3 (Organizational Project Management Maturity Model) is an effective tool to provide some solution to the problems and discuss its effectiveness.
