Which of the following metrics is NOT associated with sorting during a shift?

Picklist Adoption is indeed the correct answer as the metric that is not associated with sorting during a shift. This metric refers to the degree to which employees or systems utilize the designated pick lists to gather items for order fulfillment. It relates more to picking processes rather than sorting.

On the other hand, Sort Efficiency, Package Volume, and Sorting Accuracy are all directly tied to sorting operations. Sort Efficiency measures how effectively items are sorted within a given time frame, indicating the productivity of the sorting process. Package Volume pertains to the number of packages that are sorted, reflecting operational capacity and efficiency as well. Finally, Sorting Accuracy assesses how correctly items are sorted, crucial for ensuring that customers receive the right products. Each of these metrics plays a key role in evaluating the performance of sorting operations during a shift, making them relevant to the topic at hand.
