Tell people what you are doing and why you are doing it or don't do it at all. Ignore organizational hierarchies and structures. They change frequently, and have nothing to do with people's skills, interests, or abilities. Don't assume someone in charge knows what is best. It is easier to step around a bureaucracy, or work on something else than to waste time dealing with it.
Anarchy is more efficient than bureaucracy.
Bureaucracy doesn't scale well, anarchy does. Large organizations develop complex systems. Building software is hard. System administration is hard. Shared memory is hard.
