In this paper, I research the relationship between the free address office and the productivity of office workers, and the applicability of effective factors for the productivity of office workers in that office using questionnaire method. From the result of QAQF, the introduction of the free address office itself didn’t contribute the improvement of information exchange, creativity and morale. Therefore, the improvement of the office environment is not sufficient conditions, but necessary conditions. And, the effective personal factors and organizational factors contributed to improve the information exchange, creativity and morale in free address offices, too. So, we have to use some another measures to improve the productivity of office workers, besides the introduction of free address offices.
