Picking is a fundamental part of business logistics. Customer satisfaction depends, to a large extent, on it: if it receives the product well packaged, in good condition, with its correct labeling, etc. The picker’s order preparation activity consists of collecting and combining non-unit loads to conform a customer’s order. Picking and handling of unit loads are connected to the replenishment cycle and the prepared order shipping process. Your process of preparing and selecting items can affect the level of customer satisfaction.
