What is the outcome ensured by inventory optimization according to the text?

Inventory optimization ensures straight-line availability, which means that products are consistently available for customers without interruption. This involves managing inventory levels effectively to align supply with demand, reducing the risk of stockouts or overstock situations. By maintaining a well-optimized inventory, businesses can ensure that their offerings are readily accessible to customers whenever needed, enhancing efficiency and minimizing delays.

The other options touch on outcomes that could be influenced by inventory management but do not encapsulate the primary goal of optimization itself. For example, while improved customer loyalty can result from reliable product availability, it is not the direct outcome of optimizing inventory. Similarly, reduced staffing costs and higher guest ratings relate to broader operational or customer satisfaction strategies rather than the specific focus of inventory optimization.
