Bill of Materials (BOM)
A structured list of parts, subassemblies, and materials required to manufacture a product, including quantities, part numbers, and supplier information. Central to manufacturing and supply chain management.
Why it matters
BOM accuracy directly impacts manufacturing cost and lead time. Traditional PLM's BOM tools are cumbersome; startups like OpenBOM win by making BOM management collaborative and spreadsheet-like.
