The percentage of inactive inventory in an MRO (Maintenance, Repair, and Operations) store specifically measures the total number of items that have had no recent transactions. This metric is essential for inventory management as it helps organizations identify slow-moving or obsolete items that may tie up valuable storage space and financial resources.

By focusing on the total number of items with no recent activity, businesses can evaluate their inventory turnover rates, make informed decisions about reordering or discontinuing products, and optimize their inventory to ensure they keep only what is necessary for operations. Consequently, this percentage serves as a key indicator of inventory performance and efficiency within the MRO context, guiding maintenance and reliability practices. The other options, while related to inventory management, do not directly define the percentage of inactive inventory, as they focus on different aspects of inventory movement and status.
