To compete in today's highly complex world-with lightning--fast developments in financial markets, geopolitics, and technology arriving at an unprecedented speed--organizations and individuals must adapt to extraordinary challenges. Joi Ito, director of MIT's legendary Media Lab, and Wired contributor Jeff Howe (who coined the term "crowdsourcing"), contend that to succeed in today's marketplace, corporations must break away from the traditional command-and-control management style, and fully embrace unpredictability as a way of life. Ito and Howe have devised a set of working principles that will govern how we can--should, must--adapt to prosper in the 21st Century.
