A detailed description of the raw materials, parts, and instructions needed to build, produce, or repair a good or service is known as a bill of materials (BOM). A bill of materials typically takes the shape of a hierarchical structure, with the finished product displayed at the top and various materials and components required while making a product.
A bill of materials (BOM) in manufacturing is a list of all the components and subassemblies that go into making a product from start to finish so that it may be packaged.
In addition, it includes everything needed to ship the product to the buyer. It stores all the information necessary for manufacturing activities and also the procedures that must be performed on the product before it is finished.
Preparing a detailed bill of materials (BOM) is critical for several reasons, including guaranteeing that necessary components will be on hand and facilitating streamlined assembly.
It is helpful for minimizing wasted time and making precise acquisition order plans. Manufacturing Bills of Materials (BOMs) and Engineering Bills of Materials (BOMs) are the two most common kinds of BOMs.
In addition, inaccuracies in the BOM can lead to costly delays in manufacturing. At the same time, employees hunt down missing components, place new orders, or figure out the best way to put everything together.
Bills of materials (BOMs) can vary in structure and detail, depending on the nature of the project and the organization's requirements. The use of bills of materials (BOMs) is widespread in many industries, including engineering, operations, design, manufacturing, and others.
For example, enterprise resource planning (ERP) and materials requirement planning (MRP) systems cannot be designed without first obtaining a manufacturing BOM (MRP).
Having a bill of materials (BOM) on hand is important for both production and ordering of spares, and it helps keep things running smoothly in the event of product repairs.
The final product's design is laid out in a bill of materials created by engineers. All part numbers and components listed in the drawing notes that could be used as a replacement are included. Every line of the BOM has information about the product, such as its product code, part name, part revision, part number, quantity, description, unit of measure, length, size, weight, and specifications or features.
Engineers frequently use CAD drawings as the foundation for organizing the engineering BOM. There may be more than one engineering BOM made for a finalized product. Managing the entire lifecycle of a product includes this process.
Since the BOM's primary purpose is to guarantee proper assembly, it's important to provide detailed information on the product in the BOM file.
Here is a high-level checklist of things to include in your BOM record, whether you're making one for the first time or just wanting to refine your process:
Glue, wiring, fasteners, and other non-modelled components like labels and packaging are sometimes included in a BOM record, but many manufacturers later regret doing so. The component may not be included in the final product if not included in the bill of materials (BOM). Make sure you carefully record each of these steps.
Keep copies of relevant documents, such as CAD designs and instructions for use, as you compile your BOM. To minimize quality difficulties and manufacturing scrap and rework, it is essential to link these files with their respective components found at the proper level of the BOM.
If you want your BOM to be taken seriously, you must include as much information as possible. Even if you never meet the people who will be using your BOM, you must ensure they have access to all the information they might require at any time.
During the design phase, your BOM record may undergo several revisions. Make sure you can quickly compare the BOM from different versions to see what's changed. The bill of materials should be indented so that it is simple to see the relationship between each part and the whole.
In addition, you must be able to trace back individual engineering change orders that triggered modifications to the bill of materials (ECOs). You may now look back at the timeline of who approved which modifications and when.
Developing a bill of materials is crucial to the commercialization of a product, and it is an essential part of the product development process.
