"Like excellence, leadership is a familiar concept but hard to define because it so complex... It is one of the most observed but least understood phenomena on earth. However, leaders need to be developed at every level of the organisation to provide organisation-enhancing innovation and change. Avoid training people in 'leadership traits' which sound like thay are taken from the Girl Scouts' Oath. Managers should identify those with an extra bit of 'spark' and help them move on beyond being contributors to become leaders."
