The construction industry in Japan, one of the most male-dominant industries has been suffering from discontinuation of the employees, especially women civil engineers, and started preparing strategies which are not fully utilized. The authors proposed a human-centered design approach that employs interview, persona and scenario to derive measures which suit employees’ needs, along with a learning program to help company personnel conduct surveys and analysis so that they can revise the measures by themselves in a timely manner. A case study was conducted at a leading construction consulting firm of approximately 1,400 employees. With assistance of researchers, eleven interviews were conducted and analyzed by the personnel. Analysis derived three personas and scenarios of typical employees who face difficulty in continuing their works. Fifty-three including 36 new measures were derived to solve 36 groups of problems. Results proved that the approach was effective in deriving measures, and the program implemented in this case study was also effective for the personnel to obtain these results. However the uniformity of the interview methods such as the usages of the interview form, interviewers’ attitudes towards interviewees and estimation of the effectiveness of measures prior to their actual implementation are remained to be discussed.
