Abstract
It might be one of the difficulties of the information system integration that We must define the scope of unclear outcome. Generally We can facilitate mutual understanding by drawing, and a related person's communication based on common standards and terms. However, in the information system integration, it's difficult to promote mutual understanding between the related person because the same term has a different meaning and the different range might be shown in the same word by the type of business, business conditions, and the experience. In this paper, I analyze the gap between customer and vender generated by each phase of system construction, and report the strategy that reduces the problem.
