Order picking strategies for a warehouse
Best order picking strategies, tips and tactics
Learn how to pick faster. Here are some order picking strategies that will maximize picking efficiency in your warehouse’s pick lines, systems and processes.
Check the pick while at the slot using automation
Design your order picking strategy so that each step of the order picking process is double-checked. Humans are imperfect and so your staff will make errors. To avoid this, it is smart to double-check (and even triple-check) to eradicate mistakes. Ideally you’ll want the errors to be caught while the order picker is in place at the pick slot. If this error catch is successful at this point, it eliminates any cost associated with the mistake. To guarantee that the right pick is achieved, you will need system that includes two things:
- A scan of slot ID barcode labels and product UPC codes.
- Blind entry of the quantity picked.
Tactics to minimize selector walking
Minimize the need for selector walking by using these tactics:
- Placing slow-moving items on side aisles. Enter them only when needed.
- Pick from both sides of the aisle and be sure to use small pick facings.
- Batch pick, by picking multiple small orders in a single trip.
Ensure 100 percent product availability
Create an optimized replenishment system to ensure that any given selector will avoid dealing with an empty pick slot that needs to be filled. Also be sure the is no order segregation that cause wait timed for missing items prior to shipping. If possible, generate pick lists that show only items that are in stock at any given pick slot. Don’t waste time by having pickers correct inventory data, when missing items are discovered.
Touch picked items only once
Only touch each picked piece once. The picking process should be designed so that accuracy is ensured, and further repacking, quality control checking or shipping checking is never needed. A picked unit should go into a truck after being touched by the original picker only.
Segmentation of frequently picked items
Generate a short pick line that contain A-list items, so that 10 percent of SKUs that satisfy half of all orders. This order picking strategy results in 50 percent of all your picks through 10 percent of the pick area. Next identify 20 percent the items that satisfy 30 percent of orders. Slot these off the short pick line. As a result a majority of all orders now require travel past only 15 to 20 percent all pick slots in your warehouse.
Eliminate pick-and-pass line picking
All orders slow to the speed of the slowest picker in pass-along picking. Totes are passed along a conveyor line from picker to picker, so switch from conveyor picking to individual cart picks, if possible. Use this tactic to increase pick rates by 30 to 200 percent.
Warehouse managers must lead on commitment to excellence
Employ focused management support of workers that are responsible for picking accuracy and efficiency. This top-down tactic is the most effective way to improve a distribution design. Staff will sense immediately if managers are not committed optimization and productivity. Demonstrate this manager driven commitment, so that the whole staff understands an overall commitment to excellence.
Invest in staff training and quality circles
Warehouse productivity is undermined as customer requirements change. Your staff is your first line of defense against inefficiencies, so invest in training around productivity and accuracy improvement. Also, introduce management-supported quality circles, because these regular meetings can identify problems and reveal solutions. These practices will result in ongoing improvement.
