Summary
Effective leadership coaching can significantly improve a manager's
performance, but unfortunately, good coaching is more than just
passing on one's own business experience. Developing authentic
leadership through coaching is about changing deeply personal,
often unconscious, elements of a manager's behaviour. In this text,
Graham Lee explains to coaches how to be more sophisticated in
their understanding of psychology and how to develop the skills
needed to work on both the psychological and the practical elements
of improving managerial performance.
Leadership Coaching sets out a five-stage
coaching model, and works through each of these stages in detail,
highlighting the skills that coaches require and the issues they
are likely to face. It also offers HR managers sponsoring coaching
an understanding of the competencies necessary for effective
coaching, and provides a standard procedure for buying in coaching
services.

"If you are going to read just one
book on coaching this year, this is the one." David
Megginson, Professor of HRD, Sheffield Hallam University and
co-chair European Mentoring & Coaching Council.
"Leadership coaching has become a key to
success for both individuals and organisations. Graham Lee
demonstrates here that he is a master of the field, packing his
book with insights and practical ideas. No one has done a better
job of integrating our understandings from psychology into the
training of today's leaders. I enthusiastically recommend
this book to managers, coaches, therapists and students."
