This study analyzes how the shacho-kai (presidents’ meeting) have contributed to the competitiveness of the Japanese keiretsu network. shacho-kai had been touched upon by various literatures as one of the important elements of the keiretsu, but there had been no attempt to analyze the shacho-kai in detail with comprehensive framework. Thus, this study analyzes the shacho-kai of Mitsubishi group by applying the ABCD model, which is a framework to explain competitiveness or the success factors and compare with the case of sajangdan-hoeui of Samsung, South Korea. Samsung’s sajangdan-hoeui has shown superiority in speed and diligence whereas shacho-kai of Mitsubishi was better in synergy creation and goal orientation factors.
