I suggest you check out the outsourcing books that have come out since this one was published as outsourcing changes quickly and this one is dated and routine.
Already, better information is obtainable on current outsourcing blogs.
That happens with books though. If they are not re-released frequently and the subject matter is evolving, they fall behind as this book has done.
This book has been on my shelf for about a year and I was dismayed to learn as another reviewer mentioned before me, that the author is a for-profit consulting firm's owner who openly (verified on his site) charges outsourcing vendors to be listed in an "Outsourcing 100" listing an "application fee" of several hundred dollars and he will assure list placement if you pay him $10,000!!!!!
Sadly, its bad form and very unbiased but that is how the world turns.
The styles and intentions of Business-focused authors versus Academic-focused authors are very easy to spot. This is no exception.
Be prepared...You're being pumped to buy consulting, not make your own intelligent solutions.
On the positive side, you'll think about where you might have holes in your outsourcing strategy.
