There are quite a few cases that the lack of mutual understanding and the discrepancy of communication obstruct smooth progress in projects that have a lot of stakeholders who have a different interest. The importance of Kansei communication in the project management has recognized. In a theme of project that planners cooperate with developers, this study verified the requirement that promote a project without the discrepancy of communication between them. Concretely, we did experiment to confirm effect under the hypothesis that the role of (1) the field of review and (2) the project manager is a promotion factor in good communication. As a result, we found that (1) is effective for the decrease of a product risk and (2) is effective for the decrease of a project risk. Moreover, in the process that developers materialize planner's concept, we suggested it is possible to evaluate the state of Kansei communication in project with the content of vocabularies.
