Construction management performs a variety of tasks, and the buildup of the WBS and OBS is one of the core tasks. However, the practical utilization of WBS and OBS is low in the current construction management work. In this study, we conducted a survey of related experts to analyze the understanding, utilization level, application effect, and connectivity of WBS and OBS. As a result, it was identify that the standardization and linkage of WBS and OBS should be secured so that the construction manager (CMr) could apply it. Therefore, we extracted management control factors through expert in-depth interviews and workshops and conducted AHP importance analysis. Analysis results of importance shows that there is a high importance of strengthening the link between WBS and OBS and updating OBS due to changes in WBS. The results presented are not direct solutions, but are expected to provide a standard for construction managers to consider.
