My argument would be - greater the complexity, higher level of personal initiative and responsibility is needed.
This is not an arm-chair assertion. For example - read the works of Admiral Rickover - https://govleaders.org/rickover.htm - in buidling and managing nuclear facilities
You'll see the enormous focus on individual initiative and personal responsibility.
Heavily regimented processes are too brittle for dealing with complex problem-solving end of the day.
In fact, one way I differentiate sophisticated leader from a less sophisticated one is via the understanding of this fact: do they value individual initiative or not?
If they do not, they're not in a great position to lead complex initiatives.
