Order picking is the process of selecting and gathering items from a warehouse or storage area to fulfill customer orders. This task is essential in supply chain management, ensuring that the right products are delivered to customers in a timely manner. Workers, often called pickers, use various methods, such as handheld scanners or automated systems, to locate and collect items efficiently. There are different types of order picking methods, including single order picking, where one order is filled at a time, and batch picking, where multiple orders are processed simultaneously. The choice of method can impact productivity and accuracy, making it crucial for businesses to select the best approach for their operations.
