Abstract
Because of serious deflation prevailing in Japan, college graduate is annoyed to look for chance of employment while expert faces lay-off problem. Two principal causes are deemed to be dominant that knowledgeable worker may not transfer from declining to growing industry. Executive manager is interested in neither serious creation of new business nor methodology while individual continues to keep learning attitude or to implicitly explain experience in life-time employment environment. Competence baseline is based on the discipline by which peoples reinforce and certify hidden capability explicitly. Project Management is interdisciplinary science by which technology, practice and vocational knowledge are integrated. Body of knowledge like PMI PMBOK is well known, but ICB is slightly recognized in Japan. This paper introduces ICB discipline and finally discusses the viewpoint of intellect integration in practical interdisciplinary science.
