What is a leader? As I use the term here, the job of a leader is to accomplish transformation of his organization. He possesses knowledge; he himself has been transformed. He has personality and persuasive power. How may he accomplish transformation? First he has theory. He understands why the transformation would bring gain to his organization and to all the people that his organization deals with, the customers, suppliers, environment. Second, he feels compelled to accomplish the transformation as an obligation to himself and to his organization. Third, he is a practical man. He has a plan, step by step.
