Abstract
This paper shows that the factors contributing to the success and failure of international joint ventures such as U.S.-Japan engineering companies have been affected by information sharing and consensus building within the IJV. However, the mechanism is not simple, and contains many mediating and interaction effects between explanatory variables due to uncertainty in the environment surrounding the project. Based on existing research on risk management, it was clarified that as a research result, the factor analysis of the success and failure of IJV can be explained by applying the typical risk items of the project pointed out in P2M to the analysis model that integrates the above viewpoints.
