Abstract
Getting to say that the intangible brand power and the motivation of the staff were important in the field of the corporation evaluation which is done by the investor. As for the information service industry, too, the motivation of the personnel is pointed out as the important point of the project conduct. However, there was not a frame to take a motivation specifically and to improve it too much. We proposed the PS-investigation (it means investigation of Partner Satisfaction) to solve the problem of the motivation about the project, and we also attempted it. In this paper, we divide the Partner Satisfaction (PS) factors into the satisfactory factors and the unsatisfactory factors and the unsatisfactory factors. Then we describe the way of view of "the PS diagnosis" to join PS factors to the motivation improvement plan. Also, it reports on the case of the PS diagnosis, too.
