Serious Play: How the World's Best Companies Simulate to Innovate
Michael Schrage (Harvard Business School Press, 1999)
Schrage provides a compelling account of the role of prototyping in innovation. He describes a variety of different prototyping approaches and makes the case for companies having a conscious prototyping strategy. Although much of this book is focused on products, much is relevant to any kind of group collaboration and creativity.
