Cluster picking explained: Cluster pick is a method where workers collect items for several orders at once. This picking approach uses carts with separate bins for each order. Cluster pick helps pickers get more done with fewer steps in the warehouse, enhancing productivity and order accuracy.
Most warehouse operations waste time when pickers walk back and forth for each order. Cluster pick fixes this problem. Pickers make one trip through the warehouse to fill multiple orders at once, reducing operational costs.
Cluster picking works in many warehouse layouts. This picking method is simple to set up and brings fast results.
The cluster pick process follows basic steps that any warehouse can use. First, the system groups orders that make sense to pick together. Then pickers use carts with separate bins.
During picking, workers follow a set path through the warehouse. They grab items and sort them into the right bins right away. This sorting happens during the picking work, not after. By enabling pickers to complete multiple orders simultaneously, cluster picking significantly improves efficiency and meets high-volume order fulfillment demands.
When the cluster picking round is done, each bin holds a complete order. This makes packing faster too.
To start cluster picking, you need the right tools. Picking carts must have enough designated bins for multiple orders. These designated bins are essential for organizing and separating items, enabling efficient item collection and reducing travel time for pickers within the warehouse. Each bin needs clear labels showing which order it holds.
Mobile devices help guide the cluster pick process. Pickers use these devices to see what to pick and where to put each item. These mobile devices make sorting easier during picking.
Good mobile devices show the best path through the warehouse too. This cuts down travel time even more during cluster picking.
The biggest win with cluster pick is less walking. Pickers spend up to 60% of their time just walking in the warehouse. Cluster picking cuts this wasted time by minimizing the travel time of warehouse workers and allowing them to handle several orders at once.
Less walking means more picking gets done each hour. Your warehouse operation can fill more orders without adding staff. This makes cluster pick one of the most efficient ways to handle orders.
Cluster pick lowers costs in several ways. Labor costs drop because each picker handles more orders per hour. Shipping costs may go down too, as orders get out faster and with fewer mistakes.
Your warehouse operation saves on equipment costs too. With cluster picking, you need fewer packing stations since orders are already sorted during the picking process.
Good cluster pick systems help cut errors. Each bin is clearly marked, and pickers can check their work as they go. Mobile devices can show pictures of items to make sure the right product goes in each bin.
Fewer picking errors means happier customers and less money spent fixing mistakes. Efficient picking operations directly contribute to faster order completion and lower return rates, which are essential for maintaining customer satisfaction in the competitive ecommerce landscape. Your warehouse operation runs smoother when orders are right the first time.
Batch picking is when pickers collect the same item for multiple orders at once. All items go into one container first. Later, workers sort these items into separate orders. This is one of several picking strategies that can be used to optimize warehouse operations.
Both methods handle multiple orders, but in different ways. Cluster picking, another effective strategy, involves picking items for multiple orders simultaneously and sorting them into clusters. Integrating cluster picking with other methods, such as batch picking and zone picking, can meet specific warehouse requirements and enhance overall efficiency. Understanding these differences helps you pick the right method for your warehouse.
In cluster pick, sorting happens during picking. Each item goes straight to its order bin. In batch picking, sorting happens after all items are picked.
Batch picking works best when many orders need the same items. Cluster pick is better when orders have different items spread around the warehouse.
Cluster picking needs more equipment like multi-bin carts. Batch picking can use simpler tools but needs more sorting space and time after picking. Zone picking can be combined with these strategies to further enhance efficiency. By dividing the warehouse into zones, each picker can focus on a specific area, reducing travel time and increasing productivity. This adaptability allows warehouses to tailor their picking strategies to meet specific needs, improving the overall order fulfillment process.
Use cluster pick when:
Orders have few items that aren't the same
You want to finish orders faster
Your warehouse has items spread out
You can invest in picking carts
Try batch picking when:
Many orders need the same items
You have limited cart space
Your sorting area is large and efficient
Order timing is less critical
Many warehouse operations use both methods, picking the best one for each situation.
Before starting cluster pick, look at your warehouse layout. Check if aisles are wide enough for carts. Look at where your popular items are located. The best cluster picking routes should cover high-demand items efficiently.
You might need to move some items to better spots in your warehouse. Put fast-moving products in easy-to-reach locations. Group related items to make picking paths shorter.
Good training is key to cluster pick success. A well-implemented picking strategy is crucial in this process, as it enhances efficiency, accuracy, and order fulfillment. Show pickers how to follow pick paths and use mobile devices. Teach them how to handle picking carts without mixing up orders. Effective training and planning are pivotal components for success.
Start with small clusters of 4-6 orders per cart. As pickers get better, they can handle more orders at once. Good pickers can manage 8-12 orders in one cluster picking trip.
A good inventory system makes cluster pick work better. To enable cluster picking, you need to outline the essential steps required for implementation. This includes configuring cluster profiles, setting up work templates, defining location directives, creating mobile device menu items, and adjusting warehouse management parameters. Your system should track stock levels and locations, create efficient picking routes, and provide clear instructions for pickers.
PULPO Warehouse Management System offers cluster picking, which is ideal for multi-order picking of B2C orders with a picking cart. The right system makes all the difference in cluster picking results.
Mobile devices are must-haves for modern cluster pick operations. These tools show pickers exactly what to pick and where to find it. They also tell which bin to use for each item. A crucial feature is the mobile device menu item, which allows pickers to view their optimized pick path and manage their assigned clusters effectively. This helps streamline navigation and minimize errors during the picking process.
Good mobile devices for cluster picking should be easy to use. They need clear screens that work in all warehouse lighting. Battery life must last a full shift of picking work.
These devices track progress during cluster picking. Managers can see how picking work is going in real time. They can spot problems early and help pickers who need it.
Smart product location makes cluster picking more efficient. Put your most-picked items in prime spots. This cuts travel time during the picking process.
Consider these location tips:
Place popular items at waist height
Group similar products together
Keep heavy items in easy-reach spots
Put small items where they won't get lost
Review your location setup often. Move items as needed based on picking data. Good product location makes every cluster pick route better.
Online retailer Swybrand faced growing pains. Their warehouse operation struggled to keep up with orders. After switching to cluster pick, everything changed.
DHL Supply Chain has also seen significant success with cluster picking, optimizing their medium-sized warehouses to improve productivity and reduce congestion.
Their picking team went from handling 200 orders per day to over 800. Errors dropped by 65%. Customers got their orders a full day faster.
“Cluster picking changed everything for us,” says Swybrand’s warehouse manager. “Our pickers fill multiple orders in one trip now. PULPO Warehouse Management System guides them with the best route, and they always know which bin to use.”
This success let Swybrand grow without adding warehouse space or staff. Their costs stayed low while their business grew.
Good warehouse operations measure results. For cluster picking, track these numbers:
Orders picked per hour
Items picked per hour
Walking time vs. actual picking time
Error rates by picker
Labor costs per order
These metrics show if your cluster pick system works well. They help you find ways to make it even better.
Use your metrics to set clear goals for your warehouse. Maybe you want to increase picks per hour by 15%. Or cut walking time by 20%. Or lower error rates to less than 1%.
Look at your best pickers. What makes them so good at cluster picking? Use these insights to train other staff. Small improvements add up to big gains in efficiency.
Online stores often have many small orders. Cluster pick is perfect for this. Your pickers can handle multiple orders at once, cutting down on travel time through the warehouse.
With cluster picking, e-commerce warehouse operations can process hundreds more orders per day. This helps during busy seasons when order volume spikes.
Stores need regular shipments with many items. Cluster picking helps warehouse operations fill these orders faster. Pickers can group store orders in ways that make sense.
This picking method helps get products to stores quickly. It cuts shipping costs and keeps retail shelves stocked.
Some orders don't fit well in cluster pick systems. Very large orders or ones with bulky items can be tricky. Orders with items all over the warehouse might slow down the process.
For these cases, you might need different picking methods. Or break big orders into smaller parts that work better with cluster picking.
Order volume can spike during busy times. Your cluster picking system needs to scale up when this happens. Add more carts and possibly more pickers during peak seasons.
Plan your warehouse operation for these busy times. Make sure your inventory system can handle the load. Train extra staff in cluster picking before the rush hits.
Look for ways to make pick paths better. Study warehouse maps and actual picking patterns. Find shortcuts or better ways to group products for more efficient picking.
Good pick routes mean less walking and faster order completion. They make your cluster picking process more productive without extra effort.
The bins on your picking carts matter a lot. They should be easy to identify at a glance. Consider color-coding or large numbers to prevent sorting mistakes.
Bins should be the right size for your typical orders. Too small, and items won't fit. Too large, and you waste cart space that could hold more orders.
Start small with cluster picking. Try it with a team of your best pickers first. Pick a zone in your warehouse where items are easy to find and access.
Track results from day one. See how cluster pick changes your picking speed and accuracy. Use what you learn to expand cluster picking to more of your warehouse operation.
With the right approach, cluster pick can transform your warehouse. Lower costs, faster picking, and better accuracy are all possible with this smart method and the right system support.
