To improve forecast accuracy by reducing the information lead time from the retailer, the supplier should focus on improving the speed and accuracy of information exchange. Utilizing electronic data interchange (EDI) is the most appropriate action as it enables real-time sharing of critical data, such as sales figures, inventory levels, and demand forecasts between the retailer and supplier. This instant access to accurate information helps in better forecasting, reducing uncertainties, and aligning supply with actual demand. Other options like eliminating sales and promotions, decentralizing demand information, or reducing quoted lead time do not directly address the improvement of information exchange processes.
