The warehouse in London consists of two areas. Each area has five rows and each row consists of three shelves. The bottom shelves within a row of an area are used to store the larger items groups such as Screens, Sound Systems, Projectors and Computers. These bottom shelves need to be marked clearly as to which item belongs there. The middle and top shelves store the smaller items. Because Light & Music Ltd. often employs temporary workers for picking, they would like to be able to show and print the storage location of the item on the pick list.
