Manufacturing bill of materials

A manufacturing BOM (MBOM) – manufacturing bill of materials – lists all the materials and components needed to manufacture a specific product.

What is a MBOM?

The manufacturing bill of materials serves as a master definition that informs the organization what to make, while the bill of process (BOP) provides complimentary information explaining how to make the product.

The manufacturing BOM is generated in manufacturing process planning software within a manufacturer's product lifecycle management (PLM) system. As products across many industries have become more complex and include mechanical, electronic and software development, creating the MBOM within integrated PLM software has become essential to ensure accuracy and flexibility.

The manufacturing bill of materials is distinct from the engineering bill of materials (EBOM). However, a modern PLM ensures that all bill of materials associated with a product are defined and managed to be consistent. While the EBOM emphasizes how materials and parts relate to the product's functional design, the MBOM reflects how the materials and parts build a complete product. The EBOM is based on design data, and the MBOM on the EBOM.

Understand the benefits

Supported within a modern PLM system, manufacturing bill of materials (MBOM) software provides a complete, up-to-date source of information that eliminates the need for standalone spreadsheets and systems.

Accelerate manufacturing development

Automate the creation of the mBOM structure and provide visibility to the mBOM with downstream manufacturing domains and processes.

Rapid visualization and validation of MBOM updates

Visual and real-time eBOM to mBOM reconciliation capabilities keep data accurate throughout development and change processes.

Cost-effective, accurate execution of planned products

Plan for and validate quality manufacturing data and processes to ramp-up to production quickly.

How manufacturing BOM software works

Effectively and efficiently managing the manufacturing bill of materials has recently become more complicated for many manufacturers because of the need to maintain consistency with the EBOM and the growing customer demand for product choices and variations. An individual product definition and manufacturing BOM for each variant quickly grows to an unwieldy data set, and keeping all variant manufacturing BOMs individually up to date with any design changes is unacceptably time-consuming. Manufacturing BOM software addresses these difficulties by delivering effective bill of materials management throughout planning, development, and manufacturing.

Manufacturing BOM software provides a common source of bill of materials information across the manufacturer's organization. It allows manufacturers to coordinate upfront planning of available product options and features. It connects the product definition to partners and suppliers needing manufacturing, service, and support knowledge.

Manufacturing bill of materials software features:

  • Flexibility in MBOM definition and management built on a common, accurate product definition, up-to-date across design, development, manufacturing, and service
  • Reconciliation of the MBOM with the engineering BOM (EBOM) to ensure that engineering and manufacturing BOMs correctly correspond to the current product design or process changes
  • MBOM configuration management enables a single definition of variability, which can be leveraged throughout the product lifecycle
  • MBOM change management that tracks changes as they are being made and automatically enables traceability between change and product data and coordination of the impact of change on the bill of materials
  • Design and context management to search and filter product and MBOM information for each user's particular needs
  • MBOM visualization that allows stakeholders across the enterprise to interact with an accurate 3D representation of the MBOM
