Model-based definition (MBD) and model-based enterprise (MBE) are core Industry 4.0 technologies for digital transformation in the manufacturing industry. Legacy processes based on 2D drawings are not machine-readable, therefore, require manual intervention which increases error, time-to-market, and cost. With MBD, 3D annotated models containing geometry, product manufacturing information (PMI), and other necessary specifications becomes a single source of truth: a human and machine-readable interoperable data package consumed automatically downstream from design to manufacturing to quality to the supply chain and beyond.
This is the true definition of the digital twin and digital thread!

A number of manufacturing companies have reported anecdotal evidence describing the benefits of Model- Based Enterprise (MBE). Based on this evidence, major players in industry have embraced a vision to deploy MBE. In our view, the best chance of realizing this vision is the creation of a single "digital thread." Under MBE, there exists a Model-Based Definition (MBD), created by the Engineering function, that downstream functions reuse to complete Model-Based Manufacturing and Model-Based Inspection activities. The ensemble of data that enables the combination of model-based definition, manufacturing, and inspection defines this digital thread. Such a digital thread would enable real-time design and analysis, collaborative process-flow development, automated artifact creation, and full-process traceability in a seamless real-time collaborative development among project participants. This paper documents the strengths and weaknesses in the current, industry strategies for implementing MBE. It also identifies gaps in the transition and/or exchange of data between various manufacturing processes. Lastly, this paper presents measured results from a study of model-based processes compared to drawing-based processes and provides evidence to support the anecdotal evidence and vision made by industry.

A fully defined 3D CAD model that includes all the necessary manufacturing and inspection data for downstream consumption by software and machines without needing human intervention.
Like how the internet is more than "putting things online", MBD is an organizational change. It's beyond digitizing old problems but developing new & improved products and processes through Big Data and collaboration.
Together with Capvidia usually we recommend pilot projects that see immediate ROI and that can scale up quickly. We often see quality inspection processes as a good starting point.
Together with Capvidia we work with large OEMs and their suppliers, so we've encountered and seen all the early and lates stages of MBD.
It takes a village: design, quality, IT, internal & external manufacturing, project management, and senior management.
