As an executive recruiter, this is an excellent book for insights on starting the new job. As the executives who I place can tell you, every new job situation is different and canned formulas don't always work. I highly recommend combining this book with "Sudden Impact on the Job" by Susan Quandt - it's a powerful tandem. Quandt gets at the varied contexts under which new executives start their jobs by sharing the real-life stories of many prominent CEOs' experiences on the new job.
