Yes, this book is a must for anyone trying to devise a marketing plan and strategy. Perfectly suited to professional services but really applies to any service type business.

Some of them, it turns out, were good things to do but they weren't enough to constitute a purposeful plan or strategy. This is a brilliant book with many, many nuggets of wisdom.
