There is a balance between letting people run free, and controlling every tiny decisions. You have to keep the direction and vision, and you have to make sure everyone is going toward that. But you shouldn't trust they will do it by themselves (they may not have internalized it as much as you do either) and you shouldn't trust your ability to deal with every detail of the complex system you are trying to build. If you hired specialists that's also because you were lacking some abilities, not just because you want extensions of yourself by lack of time. And if you hired generalists that's because you needed glue to make the whole operation work with a level of understanding that you can't allocate your time to, and because you may lack the variety of skills that allow for efficient communication with the specialists.

As with any complex system, you have to be careful about degrees of freedom, too many and it can break down and too little and it can get seized.
