Jason Fried at Inc. – Why I Run a Flat Company:

"What we learned is that adding a dedicated manager and creating a hierarchy is not the only way to create structure. Instead, we decided to let the team be entirely self-managed. There's still a team leader, but that role rotates among the team every week. Each week, a new leader sketches out the agenda, writes up the notes about problems and performance, and steps up to handle any troubled customer interactions."
