Ideal governance (for companies, countries and more)

Abstract

I’m interested in the topic of ideal governance: what kind of governance system should you set up, if you’re starting from scratch and can do it however you want?. Here “you” could be a company, a nonprofit, an informal association, or a country. And “governance system” means a Constitution, charter, and/or bylaws answering questions like: “Who has the authority to make decisions (Congress, board of directors, etc.), and how are they selected, and what rules do they have to follow, and what’s the process for changing those rules?”.
