This book wants to be a self-help book. In actuality it's more of a theory book, with little in the way of practical solutions or strategies.
Ibarra states in the Preface that this book is not for everyone--it's aimed specifically at "the mid-career professional who questions his or her career path after having made a long-term investment of time, energy, and education in that path." Great, right? Actually, probably half the case studies that Ibarra presents describe people who were to my eye quite high on the career ladder, possessing high-ranking titles and running entire divisions of companies. Ibarra seems to define "mid-career" or "mid-level" differently than I would. These individuals made career changes, yes, but mostly to consulting, or to doing similarly high-ranked work at a company in a different industry. Ibarra did present some other sorts of career changers--a psychologist and author who became a Buddhist monk, a Spanish literature professor who became a stock trader and financial advisor, a finance banker who became a sucessful novelist, all of whom are mentioned in the book description, but these sorts of people aren't the main content of the book; there's much more focus on the corporate types. Across the board, all of Ibarra's case studies are exceptionally well educated white-collar professionals, and mostly they are upper class people who can afford to take a sabbatical to explore their options. What about the plumber interested in a career change? Or the real estate agent or elementary school teacher? Those careers have "mids" too, but Ibarra doesn't seem interested in them. Ibarra also doesn't tackle race as an issue in career change, and she only deals with gender so far as the case study participants themselves discuss it (not wanting to downgrade to the "mommy track", or not wanting to settle for a submissive, or helping, "female" role).
The theoretical strategies are interesting, and it's clear that Ibarra has done her research--she's a professor of organizational change who taught at Harvard Business School for many years, so she's well-versed in how to do research. Many statements throughout the book are footnoted to relevant literature, and there's an appendix detailing her interviewing and data gathering methods (a little out of the ordinary for a self-help book, but necessary in a theory book). Her theories about career change make sense, but I just didn't feel that I could relate to a lot of the case studies, so it was hard for me to connect to the theory. I was hoping for more practical pointers, too. Most of the people I know couldn't conduct a career change the way the people in the case studies do.
If you're interested in theories of career change, and case studies of well-educated professionals who undertook successful changes, then this might be an good read for you. For practical advice on switching to a new career, I don't recommend this book--try The Renaissance Soul by Margaret Lobenstine instead.
