While I would say that this book is not a "How to" guide, I feel it does an excellent job in explaining the relevant trends as they relate to Women in the workplace. This book provides the FRAMEWORK for solutions with some real world examples of how companies have worked within the mentioned frameworks. If you are looking for outright solutions (or at least a myraid of case studies), I would not recommend this book on its own.
I would even go as far as to analyze the work environment before attempting to implement any of the frameworks mentioned in this text - The "How to Begin Small Wins" section in "A Modest Manifesto for Shattering the Glass Ceiling" has some of the questions that can be used to complete this analysis.
