What is the difference between demand forecasting and demand planning?
Demand forecasting focuses on projecting future sales volumes using historical data, statistical models, and market signals. Demand planning is broader: it uses those forecasts to coordinate production, inventory, and procurement decisions across the organization. In short, forecasting predicts what will happen; planning decides what to do about it.
