Over a decade ago, ISM quoted Noel Tichy as saying that what distinguishes winning organizations is that they “teach leadership.” In that article, we called for a “culture of observation” for coaching, for ongoing conversation, and for evaluation as a process carried out every year. Interestingly, while ISM then quoted others on leadership, we said almost nothing about it ourselves. The leadership literature demonstrated, we thought, the opacity of the term. Anyone, by their own definition, could be a leader. The books written by those who espoused the highest standards of leadership (that others should thus emulate) were often on the best-sellers lists. But what it meant for our schools seemed far less certain.
