The pick list must be verified against the

A pick list is an internal warehouse document that instructs staff on which specific items and quantities to retrieve from storage to fulfill a request. This request originates from the customer order, which is the source document detailing what the customer purchased. Verifying the pick list against the customer order is a fundamental quality control step in the order fulfillment process. This verification ensures that the items being gathered precisely match the customer's request before they are packed and shipped, thereby preventing costly errors and ensuring customer satisfaction.

This paper defines the start of the order picking process as the receipt of customer orders, which are then translated into pick lists. The accuracy of the pick is measured against the original order (p. 482, Section 2.1). https://doi.org/10.1016/j.ejor.2006.07.009

The module on Order Fulfillment describes the process flow where a customer order is received and processed, leading to the generation of a pick list for the warehouse. The accuracy of this entire flow depends on fidelity to the original customer order.
