Proto- diagrams of the design environment

I’ve trying to diagram the design environment for my thesis. The purpose of this is to find ways on how my design system can be aligned to my subquestions.  This is the one that is making more sense for now:

My thesis project is about creating a fun, challenging, competitive system that provides status and encouragement to increase physical activity an social interaction in children with Cerebral Palsy.

To support the diagram above, I’m making some lists to cluster stakeholders, goals, and how design would intervene in the process to help stakeholders achieve the goals.
