MBOM and EBOM- Why They Are Important and What Are The Key Differences

For constructing, manufacturing, or repairing a product or service an extensive list of raw materials, components, and instructions is required. This list is referred to as the bill of materials. Mbom and Ebom are the manufacturing building blocs and control the manufacturing operation which is critical for the smooth functioning of the unit. Let’s analyze the difference between Mbom vs Ebom.

Reasons Why Do You Need a BOM

  • The fragility of supply chains: Supply chains stretch across continents and suppliers. It is dependent upon factors such as time-to-market and product quality. A bill of materials helps the organization plan its purchases accordingly.
  • Estimating expenses is made easier by identifying and pricing all the materials and components needed to create a product.
  • Planning and control: BOM helps in the planning of inventory by determining the exact requirement of the component.
  • Reduce waste: It facilitates efficient and accurate manufacturing and minimizes shortages and overages.
  • Minimize production delays: BOM ensures the right quantities of materials and parts, are available at the right time and the process remains as per schedule
  • Fast recovery: In case 0f product failure, it is easier to identify the root cause and make the necessary changes.

Types Of Bill Of Materials

Manufacturing materials

BOMs are significantly relevant to a modern, quality-driven, customer-centric manufacturing operation. The engineering team, manufacturing team, and services team due to the size of the production system use separate bills of materials. There may be very specific BOMs needed for a particular purpose, even though they all serve the same overall goal.

MBOM (Manufacturing Bill of Materials): Apart from all the typical BOM information such as details of parts and components. A manufacturing bill of materials includes everything required to make or construct a finished item and make it shipment-ready. As a result, it includes components, assemblies, packaging materials, and a thorough description of the steps taken to create the product. All the integrated business departments engaged in the ordering and construction of the product components have access to the information in the MBOM. The departments can be enterprise resource planning (ERP), material requirements planning (MRP), and at times, even the manufacturing execution system.

SBOM (Service Bill of Materials): A service bill of materials (SBOM) provides a list of all the serviceable parts used on a product that could influence the service of a product. In other words, it provides the detailed information required to maintain an asset while it’s in operation. Customers, third-party service providers, the manufacturer’s field service team (technicians and mechanics), and others use this information to repair and maintain a product.

Engineering materials

EBOM (Engineering Bill of Materials): An engineering bill of materials (EBOM) defines the functional blueprint of the product. It is developed during the product design process and is created automatically from engineering and design software tools such as CAD. It lists all alternative and substitute-part numbers and parts contained in the drawing notes necessary to build the product. In addition to the above, it also includes detailed engineering information, related to the product such as manufacturing tolerances. Related engineering standards and product specifications make the entire thing a part of product lifecycle management.

Difference Between MBOM VS EBOM, and SBOM

For all of them, the general Bill of Materials information around components and parts forms the base, on which each one gives additional information as per the user’s needs. The basic difference between the three is in the user and the type of information they require. Engineers want a product to be manufactured as specifically designed by them. Additionally, the operation team wants the production lines to run smoothly, and service providers are looking to offer solutions and solve issues in the most economical manner.

However, the various BOMs have one common goal to keep the teams aligned on improving manufacturing effectiveness without undue hassle and costs. They try to enhance productivity across thousands of components and dozens of teams and tasks.

MBOM VS EBOM-A Comparative Analysis Between The Two

Let’s analyze the following scenario. For instance, if a car maker wants to manufacture 500 cars:

The MBOM will be responsible for ordering or making the parts required for car manufacturing. For example steel frame, steering wheel, chassis, axel, wheels, engine, transmission system, and other parts. It will include in its list the precise quantity, exact quality, and other specifications of the materials. Any additional machinery required for the processes of stamping, welding, and painting as part of the assembly line.

In order to make the car function smoothly the systems are needed to be assembled and designed with the right components. EBOM is drafting this design and gives the structural information on how the car will be constructed using assemblies and mechanical/electrical or software parts. Specified by various specifications: 3D CAD, 2D CAD/ conventional. The interior and exterior must be fashioned in such a way that it appeals to potential buyers. Then innovative technologies need to be incorporated to make the car newsworthy and competitive with other brands. Small models will have to be made in 2D and 3D forms to test the car’s design and operation. Engineers will conduct examinations for aerodynamics, safety, hot and cold weather, fuel efficiency, electrical functionality, cost analysis, and other features.

In a market research industry, these kinds of progressive practices not only help the business to function smoothly but also grow profitably.

Bottlenecks Associated With BOMs

BOMs frequently need to modify to keep up with the dynamic changes in the manufacturing process. Updated products, changed suppliers, shifting markets, altered regulations, and more are some of the changes. This makes managing BOM difficult. Modern cloud ERP systems can be used to quickly overcome it.

Conclusion

BOMs in their various iterations of MBOMs and EBOMs are critical to the success of any manufacturing business. So progressive enterprises have started using BOMs significantly. They use it for purchasing, supply chain management, inventory, engineering, operations, and making other teams work from the same fundamental data. Modern BOM solutions bring automation, error checking, version controls, and other capabilities.
