The Second City, an improvisational comedy club that launched the careers of comedians such as Chris Farley, Tina Fey, and Steve Carell, has delivered a successful product to audiences nightly for almost sixty years. How do they do it? By recognizing the power of feedback. Brian Eno, a pioneer in the music industry who produced albums for U2 and Coldplay, relies on a feedback generation system to ensure the best performances of the bands he works with. Likewise, the lean startup movement has uncovered a similar pattern of organizations that thrive on experimentation and learning. John Krewson will describe what it means to be a feedback-based organization. He'll demonstrate how to recognize and generate feedback at all layers of an organization—individual, team, product, and strategic—using innovative techniques drawn from the entertainment industry, and he'll walk through several practices for making that feedback actionable.
