Types of BOM
Bills of materials come in several different types. What type is used depends on the industry and product life cycle. For example, producing multi-story buildings requires a manufacturing bill of materials (MBOM), but doesn't need a service bill of materials (SBOM).Here are some of the most common types of BOM's:
- Manufacturing bill of materials (MBOM): The MBOM includes a structured, comprehensive list of items and subassemblies needed to produce a finished product. It also provides information on the individual items, how they relate to one another, assembly instructions, and parts that require processing before assembly.
- Engineering bill of materials (EBOM): An engineering bill of materials defines the parts, assemblies, and parts from the engineering department's perspective. It typically provides details, including specifications, materials, tolerances, and standards. The engineering BOM shows the component structure and includes a mechanical or technical drawing of a product.
- Assembly bill of materials: The assembly BOM is a list of items required to assemble the finished product and is usually less complicated than an MBOM.
- Sales bill of materials: The sales BOM shows the items assembled at the sales phase and sold as a single sales item.
- Service bill of materials (SBOM): The SBOM is a list of items required to service an object, often machinery, equipment, or a product. It only contains information relevant to ordering the parts and servicing the equipment.
- Configurable bill of materials: Configurable BOMs meet unique customer specifications and indicate the building materials, labeling, and packaging materials. Configurable products include PCs, vehicles, and data center hardware or software.
- Software bill of materials: Software BOMs list the components of a piece of software, consisting of a mix of commercial and open-source products. They allow developers to ensure disparate software components work together and are up to date and protected from vulnerabilities.
