I've come full circle on the notion of improvisation as a source of innovation. I just finished a three day improv training program at The Second City to try to find direct application to corporate growth. I found it.
Professor Keith Sawyer makes a useful connection between innovation and learning when he writes, "What both innovation and learning have in common is adaptability and improvisationality." He connects this idea with authors Joaquín Alegre and Ricardo Chiva from the Sloan Management Review. They identified five core features of high organizational learning capability (OLC) companies: experimentation, risk taking, interaction with the external environment, dialogue, and participative decision making. Keith has found that these five characteristics also hold true of organizations that use the power of collaboration to generate innovation. He believes that organizations high in learning ability are more likely to be innovative organizations.
