Cluster Picking:

 

A pick method, typically involving piece picking and pick cart, in which a picker picks items for multiple orders from the same location to reduce travel time. For example, consider a picker with a cart that has room for nine orders, represented by carts or totes. The WMS directs that picker to a location for which one or more orders are being processed on that cart. The WMS would instruct the picker to select one or more items for the first tote/carton that needs that SKU.

After the first pick is confirmed via barcode scan, key entry or pushing a lit button, the picker would be directed to pick another item or items from that location for the next carton/tote requiring that SKU until all the picks for that SKU have been exhausted, and the picker is directed to another location for another SKU to pick.
