Understand that a bill of materials (BOM) defines the components that are required to produce a product.
A bill of materials (BOM) defines the components that are required to produce a product. The components can be raw materials, semi-finished products, or ingredients. In some cases, services can be referenced in a BOM. However, BOMs typically describe the material resources that are required. When combined with a route or production flow that describes the operations and resources that are required to build a product, the BOM forms the foundation for calculating the estimated cost of the product.
