While the concept of a BOM is straightforward, it can be complex to create, especially when dealing with products that involve numerous components. It is an important plan for building the product, ensuring everything needed is accounted for. Single-level BOMs may be used as the only guide for production in companies where the product is simple or where it contains few components or where no sub-processing is required downstream. A bill of materials with parameters allows for easy management of products with variations in color, size, components, etc.
BOMs are particularly valuable for fashion brands working with contract manufacturers, ensuring the final product meets specifications and fostering strong vendor relationships. Mistakes cost time and money, so accurate BOMs are crucial to avoid sending incorrect data to vendor partners. Because they also include time factors such as lead time and production time, they help material planners determine when to purchase as well as when to start the production of a particular item.
What to include in an effective bill of materials
Using a Bill of Materials ensures you have everything needed to complete a project or produce a product. First, review the BOM to understand the required parts, materials, and quantities. Once you know what’s needed, plan your purchases and order everything on time to avoid delays. A single-level BOM lists each component required for a product and the quantities needed, similar to a grocery list. While single-level BOMs are straightforward, they do not illustrate the relationships between assemblies, sub-assemblies, and components.
Level up your production planning with a bill of materials
A Single-level BOM is a straightforward document that outlines the assembly or production of a product without detailing the relationships between the components. This type of BOM lists each part or assembly only once and does not specify the hierarchy or interrelation of parts. It is beneficial for simple products or groups where complex structures are unnecessary. A Bill of Materials, at its core, is a structured inventory of all the materials required, parts, and components necessary to build, manufacture, or repair a product or service.
An example of a configurable BOM would be a furniture manufacturer offering coffee tables in various colors and finishes. The basic structure of the bill of materials would be the same, but the color would be configurable. The EBOM is also used by planners, purchasing, and finance to trigger purchases bom meaning for materials from existing vendors or to source vendors for new materials. They may also include drawings for new parts that will become standard in the manufacturing bill of materials. As mentioned, there are better ways (other than excel) to handle inventory. Most importantly, there are prone to errors capable of destroying an entire operation and company.
- The document should be regularly updated to reflect any changes in the development process.
- Being the case, it is also important for the procurement manager to create a good BOM so that there won’t be any issues when the time comes for buying the needed parts for the product.
- A sales BOM lists down all the components needed to develop a product that is ordered by a customer.
- The BOM is not only the list of the components but also the quantity of each component required to assemble or manufacture the product.
Part numbers and names help you identify the different components listed in a BOM. Names provide descriptive information, such as “wood leg” while part numbers like “LEG-001” provide a unique identifier for each piece. Part numbers are also commonly referred to as product codes or SKUs, and allow for detailed planning, tracking, and ordering of each piece. With BOM, you can track all the materials and components that are used in the product.
A Bill of Materials (BOM) outlines components for manufacturing a product, while a Bill of Quantities (BOQ) specifies quantities and costs of materials for construction projects. In companies where products are very technical, this may be a technical designer or product designer. In many Make-to-Order companies, it may be an engineer or an industrial engineer.

Companies need a Bill of Materials in one way or another during the entire lifecycle from the early design of a product to later manufacturing and maintenance. Each raw material is listed in detail so that there is an understanding of what should be done at each stage. The team responsible for manufacturing should be always in constant communication with stores.

It identifies the parts needed to produce a product that can be shipped to the customers. This includes the packaging for the product, as well as the waste and items consumed in the production process. This is always key for companies that practice ethical procurement when building their MBOM.
Inadequate integration can lead to data silos, redundant information, and inefficiencies. Maintaining consistency across various departments—such as engineering, manufacturing, and procurement—is essential to prevent miscommunications and discrepancies. BOM management can be a complex and demanding task due to various factors. Here are some of the primary challenges encountered when making and managing BOMs. Bills of materials serve as crucial blueprints guiding product creation, but their complexity can vary depending on the intended use. Two fundamental BOM structuring methods, BOM explosion and BOM flattening, stand at opposite ends of this spectrum.
- Conversely, a Multilevel BOM reveals the components and the relationship between them, displaying a cascading structure of how each part fits into an assembly.
- Single-level BOMs may be used as the only guide for production in companies where the product is simple or where it contains few components or where no sub-processing is required downstream.
- There’s a chance some components could look alike, so these descriptions can help manufacturers correctly identify each piece for accurate production.
- BOMs help protect product quality by ensuring all parts meet specifications; this in turn protects the customer experience, and thereby the manufacturers brand and bottom line.
The modular BOM structure provides the assemblies/sub-systems that can be selected to “configure” an end-item. The different types depend on the business need and use for which they are intended. A BOM must include the name of the product or assembly, raw materials required with quantity and units of measure, sub-assemblies, part numbers with their names and descriptions, unit costs, and product quantity. A very useful BOM format is to create a flat list of all items from multiple levels (assemblies and sub-assemblies) with the corresponding Quantities.
Also, if the production of finished products leads to the production of by-product/co-product or scrap, this can be defined in the bill of material. The multilevel BOM is more difficult to create, but it provides more detail and specificity on the product’s parent and child parts. Multilevel BOMs show the total material required, as well as relationships between parent and child products and assemblies and subassemblies.
This is the list which is used by the procurement department to maintain the stock and also to update the ERP system with BOM details. Bill of Material is a comprehensive list of raw materials, components, assemblies, sub-assemblies, parts, or anything which is required to manufacture the finished product. The finished product or goods may be the final product itself or a semi-finished product which is later consumed to produce a final or a larger product. A well-structured BOM is essential for the successful production and assembly of sustainable fashion products. By understanding the components, types, and challenges of BOM management and leveraging Centric PLM software, sustainable fashion brands can streamline their processes, reduce costs, and improve efficiency.
The type of BOM used in product development will depend on the specific requirements of the project. Engineering BOMs are typically used during the design phase, while Manufacturing BOMs are used during the production phase. Component BOMs are used to manage the supply chain, and As-Built BOMs are used to maintain a record of the final product configuration.
Because you have a list of supplies the company uses for creating the product, your procurement team won’t be looking for alternate parts, which in turn may affect the value of your company’s finished product. A bill of materials is an extensive document that will require significant time and attention. An effective BOM can improve team communication, collaboration, workflows, and inventory management. With an accurate BOM, you’ll know ahead of time exactly what you need, when you need it, and how much of it to complete your project.
Your Bill of Materials is not just a list of spare parts and machinery components but a vital asset that drives every aspect of production. The SBOM will list all the software components and dependencies within a software product to help in security and vulnerability assessments. BOM serves as a foundation for undertaking successful product manufacturing since it acts as a central reference point.
