In most large organizations, leaders can either be developed, ignored, or suppressed. Unfortunately, in many cases, rather than encouraging the emergence of leadership, it is not considered, or, even worse, suppressed.
In my career, I’ve taken over existing organizations several times. In one case, the executive I replaced was the only person in the organization that had the overall picture of what was going on. He was the one that met one-on-one with his boss to present status. His staff meetings consisted of his asking questions and handing out detailed assignments. None of his direct reports had ever been asked to recommend a course of action. Not surprisingly, when he was asked to put together a list of people in the company who could replace him, none of the people in his organization were on the list.
