The purpose of this study is to explore factors of the educational effect of the supply chain management (SCM) game. This study focuses on a beneficent influential point in SCM from prior research and the effects these points have on supply chain (SC) experts as SCM game players. For the statistical analysis, this study uses the game results of a new online SCM game named the “elephant game.” The results show that knowledge sharing between SC nodes not only reduces the bullwhip effect and total inventory cost but also changes the opinions of SC experts. Miscalculations of lead time and the existence of strategy also change their minds. Thus, this research finds important learning factors for SC experts in the SCM game. The results indicate the potential for the elephant game to be an education tool for SC experts and future SCM research.
