What inventory control system uses the oldest product first?

The inventory control system that utilizes the principle of using the oldest product first is known as "First in, first out" (FIFO). This method is essential, especially in sterile processing and medical contexts, where it is crucial to ensure that the oldest stock of items, which may have expiration dates, is used before the newer items. By following this method, organizations can minimize waste and enhance safety by ensuring that products are used while they are still effective and safe for use.

FIFO is particularly important in maintaining the efficacy of sterile supplies, as it helps to ensure that the products used have not expired and are within their designated shelf life. This system supports regulatory compliance and quality assurance standards, which are paramount in healthcare settings.

In contrast, the other inventory systems like LIFO (Last in, first out) would involve using the most recently added products first, which can lead to older stock sitting unused past its expiration. Just in time focuses on reducing inventory levels to zero or near-zero, which doesn't guarantee that older products are used first. Batch processing relates more to the production of goods or services in groups rather than managing inventory usage based on age. Thus, FIFO stands out as the method designed specifically for maximizing product freshness and safety by prioritizing the oldest
