Christian Madsbjerg and Gillian Tett, author and U.S. Managing Editor at the Financial Times, talk about silos, tunnel vision in major corporations, and why bright people do stupid things.

Gillian Tett's new book: 'The Silo Effect: The Peril of Expertise and the Promise of Breaking Down Barriers' looks at how silos are in the way of innovation and successful adaption to ever-changing markets, and uses insights from eight organizations to share how silos can be overcome.
