Forecast accuracy

Definition

Forecast accuracy refers to the degree to which a forecasted value aligns with the actual outcome. It is a crucial metric in supply chain management as it impacts inventory levels, order fulfillment, and overall operational efficiency. Accurate forecasts help organizations maintain optimal stock levels, reduce costs associated with overstocking or stockouts, and improve customer satisfaction by ensuring products are available when needed.
