I can't say how it changed me, but I can say why I like it. It is one of the most readable business books I've ever found. It's a series of stories, each compelling, and each giving a lesson from a great team. It demonstrates how work is organized into world-changing projects. Great teams come together, get the job done, and dissolve. Leadership, innovation, work environment, and other important facets of doing excellent work are all covered, in a way that the lessons stay with the reader long after he's put the book down.
