BOM

A Bill of Materials (BOM) is a comprehensive list of all the raw materials, components, and sub-assemblies required to manufacture a finished product. It's essentially a recipe for the product.

TECHNICAL DEFINITION

A Bill of Materials (BOM) is a structured, hierarchical list detailing all raw materials, components, sub-assemblies, and quantities needed to manufacture a finished product, serving as a critical input for production planning, inventory management, and cost estimation.

BACKGROUND

A bill of materials or product structure is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single manufacturing plant. A bill of materials is often tied to a production order whose issuance may generate reservations for components in the bill of materials that are in stock and requisitions for components that are not in stock.
