Picking Methods and Average Productivity Rates
What kind of productivity can you typically expect from various picking methods?
When you are working on an order picking strategy, knowing the metrics for picking rates may be helpful. Labor productivity is the key to any warehousing or order picking operation, since labor tends to be the largest single cost factor in these operations. It’s critical to understand production rates for processes that absorb labor hours, energy, money, and time.
Labor productivity metrics can vary based on specific operations in a warehouse or shipping facility, including receiving, put-away, replenishment, picking, and shipping (these factors often affect each other, which can further complicate things). The labor rates presented here are based on a cross section of analysis projects performed by Carter & Burgess. They may not apply directly to your operation, but they are a good foundation for understanding how various technologies, processes, and how your operation might perform with a variety of picking methods.

Data from within your own operation is more important than that gleaned from general analysis
By employing your own metrics, and by using timely feedback from employees, you can often make significant improvements without large capital investment. Other factors, such as facility layout, individual employee productivity, and process improvements can also weigh heavily on actual results.
