Holacracy: A Self Managing Organizational OS adopted by Zappos.

From Holacracy.org:

"Holacracy is a new way of running an organization that removes power from a management hierarchy and distributes it across clear roles, which can then be executed autonomously, without a micromanaging boss. The work is actually more structured than in a conventional company, just differently so. With Holacracy, there is a clear set of rules and processes for how a team breaks up its work, and defines its roles with clear responsibilities and expectations."

From Zappos to Google and any number of smaller organizations, companies are discovering how they can function more efficiently and adapt more quickly to changing demands in an increasingly dynamic and complex world while creating greater employee engagement and effectiveness.

Holacracy is truly unique in it's ability to distribute power, maintain absolute organizational clarity and evolve organizational structure in constant response to organizational needs.
