Planning involves deciding in advance what needs to be done, when it will be done, and by whom. It is the process of selecting the best alternative to achieve predetermined goals. Planning is goal-oriented, continuous, flexible, and forward-looking. It helps reduce uncertainty, coordinate activities, guide decision-making, and encourage innovation. Effective planning involves setting objectives, developing assumptions about the future, determining alternative courses of action, selecting the best alternative, and formulating supporting plans to implement the main plan. Regular evaluation ensures plans are achieving their objectives.
