Coaching and mentoring : what they are and how to make the most of them

Coaching has long become mainstream. Thousands of people paid GBP2,000 each to attend a three-day seminar in 2008 in London's Excel centre to listen to Tony Robbins - the man credited with 'turning around' Bill Clinton in the wake of the Monica Lewinsky affair - and discover how to 'unleash the power within'.

But the big business has been in executive coaching.

A top coach in America can earn over $15,000 a day - well beyond the normal fees charged by most consultants and occupational psychologists - and, according to Harvard Business Review, US companies are spending more than $1 billion a year on this 'must-have' activity.

A similar trend is being witnessed in Britain, where it's estimated that 100,000 managers a year now undergo coaching.

This guide explains what coaching, and its cheaper and simpler alternative, mentoring are, outlining the different types of coaching and their cost.
