Every leader in every organizations has reached their level of incompetence according to the Peter Principle. Leaders rising up the ranks eventually reach a level at which they have no experience. There are many types of leader. This is why trait theories do not stand up to scrutiny. Some leaders are charismatic, some are competent, others are not. There is no single model of a leader. Leaders must listen, learn and act. Leaders have to motivate people. Leaders have to set strategy in motion. Leaders have to be ready, willing and able.
Understanding people is necessary.
