Carsten Hansen’s Reviews > Coaching and Mentoring: Practical Techniques for Developing Learning and Performance > Status Update

This book is by no means an easy read. Unlike most business books I have read in recent years, it is extremely detailed very "text-booky" in its presentation. This means that it can be a bit heavy, occasionally dull but very, very thorough.
I found it instructive, enlightening and provided you put the required effort into it very rewarding.
