A bill of materials is a comprehensive list of raw components, parts, and sub-assemblies that are needed to create or manufacture a product. It is similar to an ingredient list in a recipe.
A BOM is viewed and used by several parties, including project or product stakeholders, industry experts, and external vendors and suppliers. Consistency in the formatting and naming of these lists is essential.
Parts List
The parts list in a bill of materials (BOM) describes all the components that go into creating a product. It includes part numbers, descriptions, and quantities. This information is used to determine the cost of a final product, and to explain it to customers. A BOM is also useful for managing the inventory of all the supplies needed to complete a project.
A bill of materials is a tool that can be used by many different people, from engineers and designers to planners, suppliers, and production. Using a BOM can save time and money by streamlining the manufacturing process. It can also help you avoid costly delays and unforeseen expenses.
To create a BOM, start with a spreadsheet and enter the information from your parts catalog. You can include the part number, description, unit price, and supplier information. Once the list is complete, you can then add the information to your product’s assembly.
A BOM is an important piece of data that needs to be managed and updated as changes happen. Instead of relying on formula-laden Excel spreadsheets that are duplicated across servers and inboxes, consider a software solution to manage your BOMs. This way, everyone can see the latest version of a product’s BOM in one place and keep track of updates as they occur. This can also improve collaboration between different departments.
Parts Descriptions
The parts in a BOM are listed and described to give people the information they need to purchase or build a product. Each part has a unique name and description to identify it. A part’s description can help a person distinguish the difference between similar items (for example, 2 1/2 “nails and 3” nails). The template should also include reference designators to identify how the part fits together with other parts in an assembly. This information is important to make sure that the product works properly.
If a particular part is used in multiple products, it may need to be listed in several different BOMs. This can be confusing, and it increases the chance that dynamic information will need to be updated in multiple locations. This can cause problems for engineering teams who must manage change to their product data.
There are other ways to organize and present a bill of materials. Many companies use specialized software for managing bills of materials. This system helps to streamline inventories and costs by eliminating the need for spreadsheets that are duplicated across server folders and email inboxes. The system also provides a centralized location for tracking and managing changes to product data. This can save a significant amount of time and eliminate the frustrations of searching for a spreadsheet that contains outdated data.
Parts Costs
For manufacturers, it’s important to keep track of all the materials that go into each product. This is the information that drives inventory management and resource planning. This template provides a great way to keep track of the raw materials, components and sub-assemblies that are required to manufacture a specific product. It also helps companies optimize warehouse space and avoid wasting expensive raw materials or working capital on unnecessary production.
Like a cook’s recipe and list of ingredients, the BOM template contains all of the information that is needed to make a specific product. It includes the part numbers, descriptions, quantities and units of measurement. Typically, the information is organized in tables with each row representing one part. The BOM template can be used for anything from a simple window assembly to large machinery and equipment.
Using a bill of materials template allows you to standardize the communication and ordering process for all projects. This ensures that all teams, suppliers and vendors are communicating the same information to accurately order the correct parts and prevent waste and delays. Additionally, it also helps control inventory levels by ensuring that the right amounts of materials are on hand for each production cycle. This also reduces warehousing and transportation costs. By following the same procedure when creating and managing a BOM, you can save time, money and resources by eliminating errors and wasted effort.
Final Result
A BOM consists of the complete list of raw materials, parts, and sub-assemblies that are needed to produce or assemble a product. It typically includes a part number, description, quantity, unit of measurement, cost and supplier information. It may also include photos and supplementary characteristics. Ideally, each item’s specifics are covered in a BOM to make it easy for procurement personnel to identify the exact part or material to order from suppliers.
The primary problem with spreadsheet-based bills of materials is the difficulty in identifying which version of a BOM is the most current or accurate. Even if you limit who can change the file by locking the Excel file or storing it in a read-only server folder, it’s still easy for people to modify and email the spreadsheet to different people inside and outside your company. It’s then nearly impossible to keep track of which BOM is the correct one before you release a new product into production.
Managing bills of materials in spreadsheets is time-consuming and error-prone. It is much better to invest some time up front in a standard BOM template and use it for all new products. Consistency will help you in the long run when you decide to move to a BOM management system, but it will also benefit your employees and suppliers NOW. When all BOMs are formatted the same way and use the same naming convention, they can be easily and instantly understood.
