This paper analyses the differences between management and confirmation to get the final products by comparative study between manufacturing industry and construction industry. As the result of it, the authors make it clear that Kouji-Kanri in Japan is limited for "fitness for purpose". Furthermore, Kouji-Kanri has the similar function as Construction Manager in the US, Clerk of Works in the UK from the view point of their business objectives. The difference between management and confirmation in construction projects is whether information process management or quality confirmation by checking products. The Japanese construction industry has been focused on not customer side but supply side like productivity increase of construction projects. This paper shows that the changing definition of Japanese Kouji-Kanri produces management procurement system, which is based on client's objectives and the nature of projects; furthermore, it has come to introduce new management style for the Japanese construction projects.
