While there are many models of leadership, we inevitably return time and again to those with emotional intelligence at the core when working with groups and individuals who wish to inspire and motivate others.
The work of James Kouzes and Barry Posner in this area is a very good place to begin.
Both highly regarded academics, it is the basis in research that makes the work of Kouzes & Posner, outlined in their book The Leadership Challenge, so well respected. Over the past thirty years the co-authors have carried out surveys and interviews with over 60,000 leaders from every industry and background and identified five practices that outstanding leaders use consistently when dealing with others.
