What allows a creative enterprise—a film studio, a design firm, a start-up—to flourish? It's an old question but one that has become increasingly relevant as we transition to an economy built on the exchange of knowledge and information. Linda A. Hill, a professor of business administration at Harvard Business School, has studied how creative teams come together and how certain leadership qualities build these collectives. Recently Hill pooled her knowledge with colleagues from Pixar, the Massachusetts Institute of Technology and other institutions to co-author Collective Genius, which offers insight into innovative groups. In an interview with Scientific American Mind contributing editor Gareth Cook, Hill describes how certain key principles, such as embracing debate, open-minded leadership and active experimentation, can allow creative organizations to thrive.
