Professor David Clutterbuck recently celebrated his 75th birthday (and published his 75th book). In this wide-ranging Masterclass he shares his good humoured and razor sharp insights from nearly 50 years of coaching and mentoring. a range of models such as The Diversity Awareness Ladder, the five different levels of interaction we have with other people; how, as a coach or a mentor, you can help people have the conversations they need to have; the problem , in the context of complexity and collaboration, of organisational reward systems that remain focused on the individual rather than the team; the challenge of organisational leaders who are unable to think systematically; the ubiquity of HR bling, for example: succession plans (that aren’t worth the paper they are written on); performance reviews (that simply provide managers with a formal structure to hide behind rather than have the conversations they need to have); the five levels of coaching which rise to (the fifth level) coaching teams of teams in large projects; where coaching enables the formal and informal conversations between teams (and where the informal conversations are the more important); the concept of rapid teaming: enabling temporary teams, which may only be in place for six months, to hit the ground running and perform from Day One; ways in which coaches and mentors will need to adapt to respond to changing contexts and technology such as AI and Automation.
