Bill of Materials (BOM)
A Bill of Materials (BOM) is a comprehensive list of parts, components, and materials required to build, assemble, or repair a product or system. It is used in maintenance operations and management to identify the parts and materials needed to complete a work order, as well as the quantity and cost of each item. BOMs are typically organized hierarchically, with the top-level item representing the finished product and each subsequent level representing the components and sub-components that make up the product. BOMs are also used to track inventory levels, plan production, and manage purchasing.
