Using simulation to teach business related concepts has been shown to improve student performance and learning. Developed almost two decades ago, an Enterprise Resource Planning (ERP) simulation game has seen wide adoption in traditional classrooms. However, report of its use in online classes has been rare. This teaching note shares experiences in using the game in an asynchronous online environment. Students in two separate online MBA classes were evaluated through a pre-test post-test knowlede measurement. The findings were that there was a significant improvement post-game to their knowledge pre-game. In addition, students reported that they were highly satisfied with the experience and that they considered the game an effective learning tool.
