A bit dated (2006) review of state of collaboration at a point in time. I was hoping for more analysis of what makes for successful collaborations. Like most business books a set of case studies are presented and cheerleading of how wonderful collaboration is and how it made the companies wildly successful. But as with all other business techniques, some people do it well and some poorly and most muddle through in the middle ground and I didn't find enough meat in the author's opinion on what distinguishes one from another in this book.
