What are MBD and MBE, why are they important?

Model-Based Definition (MBD)​: System and techniques to define business products and processes using digital data instead of documents. MBD is often used in the context of digital 3D model data.

MBD goals:

  • Digital data as master/authority definition
  • 3D model-data as master/authority
  • Reuse model data
  • Eliminate documents​
  • Eliminate 2D drawings​
  • Eliminate waste
  • Enable direct use of information
  • Increase productivity, ​quality, and value of time spent
  • Decrease cycle time​
  • Decrease learning curve and hidden costs of drawing-related training
  • Reuse and learn from data​

Model-Based Enterprise (MBE)​: The organization focused on using MBD as much as possible throughout the product lifecycle

MBE goals:

  • Optimize benefits of MBD and digital information
  • Provide the maximum benefit of MBD to all business activities 
  • Eliminate documents
  • Eliminate low-value manual activity
  • Enable all staff to efficiently use digital data in all activities
  • Reuse, refine, add to, and learn from data as much as possible
  • Automate, innovate, elevate

Why MBE?

Model-based enterprise (MBE) is a term used in manufacturing to describe where an annotated digital three-dimensional (3D) model of a product serves as the authoritative information source for all productITI - International TechneGroup activities lifecycle.

MBE's strategic benefit is to replace digital drawings. For example, a single 3D model contains information found in an entire set of engineering drawings, including geometry, topology, dimensions, tolerances, materials, finishes, and weld callouts.

MBE was championed by the aerospace and defense industries, with the automotive industry following. Since MBE has come about, many manufacturers have adopted MBE worldwide in a wide range of industries. 

Significant benefits for manufacturers include reduced time to market and savings in production costs from fewer overall assembly hours, less rework, streamlined development, improved tool design and fabrication, and better collaboration on engineering changes.
