Abstract
This paper attempts to investigate how Work Breakdown Structure (WBS) has been applied to communication management. Based on our comparative study of communication management with WBS in a construction project, we can observe three facts. First, although the number of communication increased through the whole project, the frequency of WBS usage became decreased. Second, WBS has been used to closed information processing and the vertical communication channel with hierarchy. Third, WBS has shared with few stakeholders. The author supposes that it would be caused by the content of information or message with WBS.
