Sometimes as good as a developer is they don't understand the whole business goal. You kind of need to be hands on at some points. Maybe not in terms of how the database should be structured but maybe some parts of UI. It's funny developers like to go at it on their own but they are too smart for their own good and what they find to be the obvious interaction is something most people will never perform.
You need everyone to understand when to be hands on and where to be hands off.
