Tremendous.
This book will amaze you - not only the level of corporate rot and dysfunction, but how determined one must be to get around it. It may give you some ideas for your own Intrapreneurship. Another amazing fact is how people and companies just refuse to learn, no matter what is placed in front of them or how obvious reality is.
Don't underestimate the need for a halo project, in either your corporate or personal life. And don't rip the team of crazies, because they're the passionate ones that come up with new Corvettes (and Apple Macs, and Tivoli software, and SR-71s, and so on).
