Which system involves rotating items in the storeroom based on the date received to use the oldest product first?

The system that involves rotating items in the storeroom based on the date received, ensuring that the oldest products are used first, is known as FIFO, or "First In, First Out." This inventory management technique helps reduce waste by ensuring that older stock is utilized before newer stock. In the hospitality and tourism industry, where perishable goods are common, FIFO is particularly important for maintaining food safety and quality. By adopting this method, businesses can minimize spoilage and maintain the freshness of their offerings, which is crucial for customer satisfaction and operational efficiency.

In contrast, other systems like LIFO, which stands for "Last In, First Out," prioritize the use of newer inventory rather than the oldest, which can lead to older stock becoming outdated or spoiled. LEED is focused on sustainable building practices and does not pertain to inventory management. SOP, or Standard Operating Procedure, refers to established guidelines for processes, rather than a system for managing inventory based on receipt dates. Therefore, FIFO is the most effective approach for the scenario described.
