The book was written by Neil Benson who is a recognized Dynamics CRM expert. Neil has produced a book that is of benefit to those preparing for the MB2-866 certification exam and consultants. I believe Neill’s in depth knowledge of Dynamics CRM shines through in this book especially in the summaries which include some useful tips and gotchas.
For those studying for the exam it contains exam tips, sample exam questions and self test questions. I would have no hesitation in recommending this book if you going to sit the exam.
