Bill of materials: the list of components and quantities needed to make a product.
A bill of materials identifies the components needed for a product or assembly and the quantity of each required. Production planning and procurement use that structure to establish material requirements. Checking it against the intended product helps reveal missing components or incorrect quantities before they affect manufacturing. Changes to the product need to be reflected in the relevant material records. A BOM describes what goes into the product. A routing describes the manufacturing operations, so the two documents serve different purposes even when they are used together.
