As retail environments become more competitive, manufacturers experience greater pressure to strike a balance between satisfying customers and minimizing costs. These suppliers struggle to accurately predict or forecast demand for goods. A new study by a University of Arkansas logistics researcher confirms that relying on retail point-of-sale data can increase the accuracy of predictions and reduce forecasting error. But contrary to recent findings, the new study also revealed that in specific situations point-of-sale data might not be as accurate as simple order data from client stores.
