There are several issues related to inventory management and forecasting at the Exchange. Manual data entry into the warehouse management system leads to many errors in expiration dates. There is no standard for barcodes with expiration information. Buyers forecast based on historic data and inventory levels, which can be incorrect. The Exchange struggles to meet demand for popular high turnover items. Seasonal items have long lead times but demand is difficult to forecast accurately, resulting in excess inventory, spoilage, and shortages. The warehouse space is not utilized efficiently due to excess inventory.
