Kitting is an assembly and manufacturing process in which separate but related items are grouped, packaged, and bundled together as one unit. For example, in PC assembly, the kit is made up of a predefined motherboard, chassis, memory, drives, peripherals, and software. The user will consume and combine these items through an assembly/manufacturing process to produce the finished kit, which then becomes inventoried stock. Each individual stock item that forms the kit is issued out of inventory and the kit that was created becomes one inventory item. Kitting also works with advanced stock inventory such as perishable medicine or food with expiration dates and hardware components with batch or lot numbers.
