I kid, but I think the early proponents of Scrum and similar were trying to achieve a loose framework to do exactly what you’re talking about. The modern incarnations of these can be horrific, but the original intent was always to empower teams to make their own process. Ahh well.

Like so many good ideas (democracy, constitutions), you only really know how well they function once people are actively trying to subvert them. Scrum et.al. have failed in the face of corporatocracy. I honestly don’t know if decentralised structures (i.e. teams empowered to run themselves), can ever survive in large corporates. Which is a pity. Cities grow, but companies die. You have to jump off the dying colossus to find the new company that hasn’t yet succumbed.
