How can shelf life be improved for inventory items?

  1. By increasing inventory turnover

  2. By lubricating or rotating critical components

  3. By implementing automated storage systems

  4. By reducing the amount of inventory on hand

The correct answer is: By lubricating or rotating critical components

Improving shelf life for inventory items is crucial for maintaining quality and preventing wastage. Lubricating or rotating critical components plays an essential role in this context, particularly for items that have a shelf life affected by environmental factors like wear or chemical degradation. Regular lubrication helps prevent rust, corrosion, and physical wear, thereby extending the usable life of machinery and equipment. In addition to lubrication, rotating inventory items ensures that older stock is used before it reaches its expiration date. This practice mitigates the risks of having items degrade while sitting unused, thus contributing effectively to maintaining the overall quality and longevity of the inventory. While increasing inventory turnover and reducing the amount of inventory on hand may help manage shelf life indirectly by minimizing waste, they do not actively improve the quality of the items being stored. Similarly, implementing automated storage systems can enhance efficiency and tracking but does not intrinsically improve the physical condition or shelf life of the items themselves. Thus, focusing on the maintenance and proper handling of critical components is vital for extending shelf life directly.
