Love this mediation on maps, mapping and managing complexity in projects from Dark Matter Labs:

Maps are not simply means of sharing our work publicly. They are a central part of our inquiry process. They allow us to share our individual thoughts, explore connections and work collaboratively. Our daily work often involves moving between projects and holding multiple pieces of information simultaneously, and maps serve as a vessel for retaining that information. Different team members can enter a project, introducing new ways of thinking and spotting a host of new connections.
