A manufacturing bill of materials (MBOM), also referred to as the manufacturing BOM, contains all the parts and assemblies required to build a complete and shippable product. MBOM is a type of

(BOM). Unlike engineering bill of materials (EBOM), which is organized with regards to how the product is designed, the MBOM is focused on the parts that are needed to manufacture a product. In addition to the parts list in an EBOM, the MBOM also includes information about how the parts relate to each other. In a batch execution system such as ISA-88, the MBOM will refer to the

terms, the MBOM will refer to the "material specification" in the "product definition model". An MBOM is not the same as "as manufactured" or "as built". The MBOM can be viewed as the ingredients in a recipe to make a cake, where as "as built" refers to the actual materials that were consumed to make the cake. In ISA-88 terms "as built" is the same as the batch record, in
