Planning involves determining objectives and strategies to achieve goals. It provides direction, encourages innovation, guides decision making, and facilitates control. Planning is important for organizations as it identifies courses of action, efficiently utilizes resources, and determines opportunities. There are different types of plans including strategic plans and operational plans. Strategic plans are long-term plans made by top management to determine overall objectives and how to achieve them, while operational plans direct day-to-day operations to accomplish strategic objectives. Barriers to effective planning include lack of commitment, unclear objectives, failure to understand scope, and lack of management support. These barriers can be overcome through organized, clear, and participatory planning.
