Decision making is the process of examining alternatives and choosing a course of action to achieve objectives. It is a systematic, logical, and rational process that depends on the situation. Decision making involves individuals and groups in organizations. In schools, the decision making process involves the school head, assistants, teachers, and sometimes students, with the final decision taken by the school head. The steps in decision making include fully analyzing problems, considering alternatives, and choosing the best decision based on intelligence, experience, and the environment. Participative decision making involves all personnel and has advantages like improved decisions, broader perspectives, and easier implementation, but can be time-consuming.
