Decision-making is the process of selecting a course of action from alternatives to achieve desired goals. It involves identifying problems, gathering information, developing alternatives, evaluating alternatives based on criteria, and implementing a solution. Effective decision-making requires accuracy, considering the environment, timely decisions, communicating decisions, participative decision-making, and implementing decisions. It plays an important role in management. Challenges can include incomplete information, an unsupportive environment, lack of acceptance by others, ineffective communication, and incorrect timing.
