In Keep the Family Baggage Out of the Family Business, family business expert Quentin Fleming has identified the Seven Deadly Sins that are invariably responsible for a family business's demise. Keep the Family Baggage Out of the Family Business presents practical and accessible advice geared toward the average family business owner or employee and is an invaluable tool for helping family businesses not only survive but thrive.
Nonetheless, I recommend the book. My usual use of the book is education of non-family managers who work for family business. My favorite reading references for professional managers are by John L. Ward: Keeping the Family Business Healthy, and his revised, expanded update, Strategic Planning for the Family Business.
Family members may be willing to read the book, although I have limited experience with that. I would refer them to books like Working With The Ones You Love by Dennis Jaffe.
