Suppose there are 500 craftsman working together on a project because it too big for a smaller group to handle. How do they divide work? Especially when it comes to the work that everyone wants to do, or the work that no body wants to do? How do they resolve disagreements about what 'better' means? If caftman-1 says that craftman-2's performance is holding him back, while craftman-2 says that craftman-1 is asking him to do too much work, who adjudicates? What is a reasonable basis for a judgement?
Again, I'm honestly asking because I don't know. Large human organizations seem to repeatably converge on similar design patterns, but if there's a better way, I want to know it.
