Abstract
Information Technology Skill Standards (ITSS) are the indices which identify and systemize practical abilities for IT services. ITSS was published by the Japanese Ministry of Economy, Trade and Industry(METI) in December 2002. Since then, it has come into widespread use as indices of skills of human resources among companies in the IT service industry. Our previous work analyzed the documents of ITSS using data mining techniques, but a proof or evaluation of the results is required. This paper compares between the results of the previous work and the results of a questionnaire that was applied in a Japanese company that uses ITSS to develop its human resources. The questionnaire was applied to 1080 employees in 15 departments in a Japanese company. The purpose of this questionnaire is to grasp the skills of the employees. The correlation coefficient between the questionnaire and the previous work is 0.67 and this is good value. This proves that the results of previous work is very near to the real life.
