Manufacturing BOM
The bill of materials that reflects how a product is physically assembled in manufacturing, including manufacturing-specific part numbers, assembly sequences, and work instructions — distinct from the engineering BOM.
Why it matters
The MBOM is the link between what engineering designs and what manufacturing builds. Misalignment between EBOM and MBOM is a leading cause of production errors and cost overruns.
