I think this post comes with the assumption that organizations and collaborations need to be efficient, in a traditional sense. If you go with that assumption, then clearly someone needs to be in charge to do all of the decision making. But don’t you lose the purpose of collaboration (= working together) then? What’s the point in collaborating on something if one member has more power than the other/s and sets the mission on their own? I believe it’s better to work and talk things out together, so you can expose and move away from your own biases and broaden your horizons together. Of course that takes time and isn’t an efficient way of working in an organization if your only measurement is time spent.
