The CHAOSS project represents a potential force for power and good in open source and is demonstrating significant progress toward its stated aims during its first four years. In particular, the CHAOSS project advances the development of metrics and programs that can help other projects to first understand their own diversity, equity, and inclusion and second work to improve their project in these areas. This roundtable includes speakers who took part in a year-long reflection on DEI practices within the CHAOSS project. The roundtable talk will help other open source projects in their work towards improving diversity, equity, and inclusion by exploring practices within the CHAOSS project first, then using those examples as points of reference for other projects. In particular, the roundtable talk will advance these goals, aimed at answering the question of: How do we design open source communities to be more diverse, equitable, and inclusive?
