CPFR is also an extranet system developed for sharing logistics management processes with suppliers, and it enhances VMI and continuous replenishment by incorporating joint forecasting. SC partners exchange information related to past sales trends and scheduled promotions, fore-cast future market development and customer behaviour, and even share opinions and suggestions. The system contributes to SC partners by focusing on their core business values and benefiting from each other. Like EDI, CPFR can also improve SC efficiency, increase sales and timely responsiveness to markets and customers, and reduce fixed assets investment and inventory costs.
