The warehouses doesn’t add any extra value to the items themselves but only to customers by give it in the time that the customer wants it, in the right amount and in the right quality. This makes the processes in the warehouse that is necessary for maintaining that ability: necessary non-value added processes. The warehouse can also be preferred for distribution purposes. But since nothing the warehouse do with the item give it more value in monetary terminology, little handling of the item as possible is to be preferred. But as mentioned before there are necessary non value added processes and there are those who are just non value added. The goal is to avoid the non-value added activities and improve the necessary non-value added processes if they can’t be avoided as well.
