If you cut off a spider's leg, it's crippled. If you cut off its head it dies. But if you cut off a starfish's leg it grows a new one and the old leg can grow into an entirely new starfish. Some organisations are as decentralised as the starfish, with no control or grand strategy, such as Craigslist and Napster who both were originally run by their customers. This new book proves that this type of leadership is primed to take over the world. Major companies are starting to decentralise with great results. This is a guide to the theory behind decentralisation.
