You know the pareto concept – 80% of the productivity can come from 20% of the operation. That also applies to floor space in many warehouses and industrial operations.
One easy way to save space in your warehouse is to look for big, open spaces in your rack system. If you have pallet racks but not all of your inventory goes into full pallets, one quick way to save space is to use that rack space for higher productivity activities. Could you move each-pick or case-pick operations off of floor pallets or static shelving into flow storage embedded in your racks?
