Instead of allocating a picking job by carrier or similar, you can say to your WMS:
- "I want to pick 100 orders at once and not with any uniqueness."
The WMS then spits out a list of all the products contained in these 100 orders. You get your route and start your picking mission.
When all products are picked, you stop at one side of the put-to-wall solution. Only here you scan the products, which in the same second lights up a lamp at the compartment where you will place the product. You repeat this with all the items in your cart while your colleagues do the same. This means you can make fewer but larger picking rounds/day = fewer steps = not visiting the same place over and over again. We call it a "chaos pick".
Once on the other side of the framework aka Put-to-wall, the light will only come on when the order is complete to proceed. Most often this means packing the order, which makes it beneficial to have the packing tables right next to one side of the put-to-wall. This is also a good way to keep track if you are doing cross-docking. Being able to finish picking all of the order's "friends" and then, when the last piece of the puzzle appears, being able to quickly get the order out creates customer satisfaction in the end.
