The document discusses collaborative planning, forecasting and replenishment (CPFR). CPFR is a business practice where trading partners work together on planning and fulfilling customer demand. It aims to increase availability for customers while reducing costs. The key elements of CPFR include joint business planning, sales forecasting, order forecasting, and resolving any exceptions collaboratively. CPFR follows a cyclical process where trading partners jointly create sales forecasts, order forecasts, identify exceptions, and resolve them to continuously improve forecasts.
