  • A Study on the Key Success Factors to Form a Business Ecosystem, Sadaharu TEZUKA, Journal of Japan Association for Management Systems, 35巻, 3号, 221, 228, 01 Mar. 2019, Journal of Japan Association for Management Systems, As the business environment becomes drastically competitive, a "business ecosystem" which stands for a concept to form interactive relationships among organizations and individuals has been popular since the 2000s. The "business ecosystem" aims at building a sustainable competitive advantage. The formation of a business ecosystem is more important for venture companies with their limited business resources. In this paper, after reviewing previous studies on the concept of a business ecosystem, hypotheses on the key success factors of a business ecosystem are assumed by using studies on a dyadic alliance, and then they are verified by a case study on the Japanese venture company.

  • An Analysis on Key Success Factors of Different Corporate Alliances: R&D-Based Venture Company Cases, Sadaharu TEZUKA and KIyoshi NIWA, Journal of the Japan Society for Management Information, 12巻, 2号, 1, 19, 01 Sep. 2003, the Japan Society for Management Information, 丹羽清, Many previous studies have indicated various types of Key Success Factors (KSFs) of corporate alliances, however, all the studies argue from a comprehensive point of view and do not analyze the KSFs according to differing corporate alliance models. Thus, in our study, we look at the KSFs from four perspectives: objective, competition, type of business and scale of partner. Evidence for this is based on results from questionnaires and case studies to R&D-based venture companies.

  • Knowledge Sharing in an Alliance Community: R&D-Based Venture Company Cases, Sadaharu TEZUKA Kiyoshi NIWA, Journal of The Japan Society for Management Informarion, Vol. 10, No.1, 81, 100, 01 Jun. 2001, the Japan Society for Management Information, 丹羽清, It is important for corporate alliances not only to make up for lack of resource but also to share knowledge among their members effectively. Based on previous studies by Nonaka (1990) and Matsuda (1990), we use the concept of “inter-organizational intelligence,” to analyze the knowledge sharing mechanism in an alliance community. Through case studies and the results of questionnaires, this paper shows that inter-organizational intelligence is different from organizational intelligences in terms of creating business planning skill, which is connected to the success of alliances, and that inter-organizational intelligence is formed through two steps.
