Decentralized systems, on the other hand, are a little trickier to understand. In a decentralized organization, there's no clear leader, no hierarchy, and no headquarters. If and when a leader does emerge, that person has little power over others. The best that person can do to influence people is to lead by example. Nevins calls this an open system, because everyone is entitled to make his or her own decisions. This doesn't mean that a decentralized system is the same as anarchy. There are rules and norms, but these aren't enforced by any one person. Rather, the power is distributed among all the people and across geographic regions. Basically, there's no Tenochtitlan, and no Montezuma.
