Abstract
Organizational improvement of project management is necessary to prevent project failures. PMO is established to promote this improvement on enterprise level. The activities of PMO are based on the cooperation with a project team, which greatly affects the improvement of project management. This paper describes the case of exploring problems to improve the cooperation through the "HONNE" discussions by using SSM (Soft Systems Methodology (P. Checkland, 1981)). And it is shown that SSM is the effective process which improves the situation of a project.
