BOM (Bill of Materials)

A Bill of Materials (BOM) is the structured list of all components, sub-assemblies, materials, and quantities required to build a product. In PLM, the engineering BOM (eBOM) captures design intent, the manufacturing BOM (mBOM) reflects how the product is built, and the service BOM (sBOM) tracks what's installed in the field. BOM management is the core governance function of any PLM system.
