Lean simulations provide a critical “aha moment” that helps with the understanding and buy-in of key lean principles. The purpose of this article is to share the process of development and implementation of an ongoing international on-line Lean-IPD simulation experimentation community called Administering and Playing Lean Simulations Online (APLSO). The group emerged following the arrival of the COVID19 pandemic to include academicsfrom 38 universities(70%) and consultant practitioners (30%). This paper documents the inception and growth of this community so that lessons learned can be shared with the international lean construction community. Serious games and simulations were transitioned to an online format, relying heavily on commonly available software such as Zoom™ and Google Slides™. The most frequently developed simulations tended to be those most typically played by academics and consultants prior to the pandemic. The authors classified games presented, as well as identified physical simulations still needing to be converted to an online format.
