Bill of Materials (BOM)

A Bill of Materials (BOM) is a structured list of all components, subassemblies, raw materials, quantities, part numbers and specifications required to build a product. It functions as the single source of material and assembly information used by design, procurement, التصنيع and maintenance for costing, sourcing and change control. BOMs are typically hierarchical (multi-level) and integrated with CAD/PLM systems to manage revisions, traceability and lifecycle workflows.
