The document discusses different types of planning used in organizations, including strategic planning conducted by top management for long-term goals over 10 years, operational planning by lower management for current activities over 1 week to 1 year, and short-term planning for less than 2 years to keep the business running day-to-day. Formal plans are written while informal plans are conceived mentally, and standing plans are used repeatedly as routine plans while single-use plans address specific circumstances.
