How to Create a Maintenance Bill of Materials BOM

Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years. While there are many benefits of preventive maintenance, long-term success can be difficult to achieve. Follow these preventive maintenance best practices to improve your PM practices and increase the reliability of your equipment and facilities. Spreadsheet programs such as Microsoft Excel are popular and great for simple data collection and organization. However, spreadsheet software has limitations in terms of automation and ease of use. Though the tool is digital, many updates must be made manually, and it takes someone computer-savvy to set up special formatting, equations, and styling.

For example, your supply chain team does not need your part numbers, so you only need to share a portion of the BOM data with them. Manufacturers use their BOM to inform the downstream operations on what they need to execute. It goes without saying that providing accurate information to other teams and employees is crucial; otherwise, your downstream operations team could order the wrong parts or produce an incorrect revision. There are two options for the front cover (metal and plastic), two options for rubber strips (dotted and lined), and two options for ink color (blue and red). We have to select one option from each alternative to make a final product.

  1. A bill of materials is an important part of the engineering and manufacturing process.
  2. Asset tagging increases the visibility of your organization’s assets, leading to improvements in asset tracking and asset maintenance management.
  3. BOM flattening is particularly useful when presenting summaries to stakeholders or for preliminary discussions, as it emphasizes the main components without delving into granular details.
  4. Many organizations use facility management and maintenance management interchangeably, but the two are not the same.

You should try to include any information that will help ensure all materials are available when needed – for instance, including often forgotten items such as adhesives. If a change is made to the assembly, it affects the subassembly and its components. In multilevel BOMs, the structure is often referred to as the “parent” for the assembly, and the “child” for the subassembly, as they are related to one another. It basically works like a recipe, where all important ingredients are listed. Due to its simplicity, the single-level BOM is not suitable for large-scale production, especially complicated end products.

What are the advantages of using a BOM?

Looking at the indented bill of materials example, it’s largely due to a manufacturer having to follow not only the production of their finished goods but also their subassemblies. Subassembly can be described as several components put together to make a unit, which can then be used as a part for a larger assembly bom meaning or a finished product. A subassembly can also function as a finished item sold separately to customers or used to finish constructing another product. If you are a manufacturer with complex production processes, utilizing BOM software integrated with an ERP solution should be a serious consideration.

They could be denied due to a low appraisal or something involving their personal finances. Either way, the seller could still put the property back on the market if the buyer backs out due to a financing issue. This BOM will list the quantity and type of flour, the quantity and type of butter (or oil), the quantity of salt, etc.

Without a BOM, manufacturing operations must create workarounds to determine valuable information related to production and assembly. An accurate and effective BOM streamlines the production process by providing a roadmap or recipe for each finished good, freeing up valuable hourly and management time to commit to the process of production. Here, discrete manufacturing implies that finished products are made of components or raw materials that are capable of being touched and counted. This includes joining, attaching, fixing, assembling etc. and finished products produced here are capable of being broken down and disposed it as parts or re-use it. A bill of materials (BOM) is an extensive list of raw materials, components, and instructions required to construct, manufacture, or repair a product or service. A bill of materials usually appears in a hierarchical format, with the highest level displaying the finished product and the bottom level showing individual components and materials.

A bill of materials (BOM) is a comprehensive inventory of the raw materials, assemblies, subassemblies, parts and components, as well as the quantities of each needed to manufacture a product. In a nutshell, it is the complete list of all the items that are required to build a product. BOM explosion involves dissecting a high-level BOM into its minutest components and materials. This process is essential for precise material planning, accurate cost estimation, and efficient procurement. By unraveling the hierarchical BOM structure, manufacturers gain a clear understanding of the intricate web of components needed, streamlining the production process and ensuring quality control. Engineering software and Product Lifecycle Management (PLM) tools play a pivotal role in automating this explosion process, transforming intricate designs into actionable production plans.

Why Use a Bill of Materials?

A BOM typically has a hierarchical structure with the finished end product at the top. It includes product codes, part descriptions, quantities, costs and additional specifications. BOMs are also useful for companies that run lean production and continuous improvement-based processes. The upfront blueprint that a BOM provides helps avoid wasteful production errors.

Manufacturers of complicated electronic products must manage, track, and store hundreds—if not thousands—of parts in their product development processes. And every time a new part is added to a company’s library, it can cost $15k in time and effort to qualify and rollout. For product companies working with distributed teams and supply chain partners, collaborating on the latest bill of materials (BOM) is critical to reduce production errors and shipping delays. This is a simple list with each assembly or subassembly needed for a product shown once, with the corresponding quantity required for each product. However, this type of BOM is unsuitable for complex products because it does not specify the relationship between parent and child parts and between assemblies and subassemblies.

Instead, what will happen is if a sales order is generated, Katana’s real-time master planner will automatically allocate available finished goods to the order so that you can fulfill it as soon as possible. However, if you select the materials tab, you can see all the components which have been used to make those subassemblies. This means you’ll need intimate knowledge of your materials, components, and subassemblies to develop your indented bill of materials.

It’s a comprehensive list of all parts and materials required to build a product, and an accurate BOM is vital to reducing waste, streamlining production, and ensuring the availability of necessary parts. Bills of materials facilitate efficiency and help companies manage their operations costs. The manufacturing BOM (mBOM) is used when a business needs to show all of the parts and assemblies required to build a finished product. Parts that require processing before assembly must also be included in the mBOM.

Creating a bill of material management process requires certain information. Here’s a list of questions you should ask to gather the relevant information. One of the main goals of BOM is to ensure that you build the product right.
