3 ways of getting things done.

There is this unpopular book called "3 ways of getting things done" which I think sums up all power relationships, though I would redefine things just a little.

Hierarchy: Superiors issue orders to subordinates and they obey.
Democracy: Voting or some other system of representation.
Autonomy: Individuals or groups are allowed free reign, usually in the context of certain boundaries and limitations.

I don't know what the big deal is, it seems pretty straight forward to me, we need to use the best system for the task or 2 or 3 when we are unsure. What is the need for all these ideologies?

>Democracy: Voting or some other system of representation.

Only representative democracy is a system of representation. Real or Direct democracy uses delegates.

>Autonomy: Individuals or groups are allowed free reign, usually in the context of certain boundaries and limitations.

The underlined parts are quite contradicting don't you think?
