Developmental organizations face challenges in ensuring the sustainability of their interventions in rural communities. Community knowledge and healthy social and political systems are essential in designing effective interventions. In this research, I discuss the issue of limited access to essential technology among women from rural communities and the need to design technology from the end-user's perspective. Over the course of this thesis, I propose OurOS as a tool based on design justice principles that involve stakeholders, including community members, development professionals, and government employees, in co-designing innovative solutions to the wicked problem of sustaining community support. The tool is framed as a tabletop game that is played to facilitate discussions among stakeholders to co-create a plan of action for building a sustainable community. By constructing a collaborative approach that involves all community members, I argue that developmental organizations can create interventions that have a lasting impact on rural communities.
