Collaboration is a fundamental yet underappreciated force in business, the arts and sciences. Most organizations lack structures that allow people to pool their talents creatively. In place of the bastardized American notion of "teamwork," Michael Schrage advocates genuine collaborative interaction aided by "shared spaces" like blackboards or brainstorming sessions. Schrage has written a trailblazing guide to help people in diverse fields move from mere communication to true collaboration. Snippets on such duos as Picasso/Braque, F. Scott Fitzgerald/Maxwell Perkins and Francis Crick/James Watson (co-discoverers of DNA's double helix) throw light on the collaborative process.
