In the context of a Model-Based Enterprise (MBE), modularization plays a pivotal role in achieving data continuity and operational efficiency. A Module represents a strategic, functional building block designed with standardized interfaces to support scalable product architectures. To address specific customer needs and meet business objectives, Module Variants are defined and controlled by configuration rules that ensure consistency and reusability. These Module Variants become the backbone of digital product structures and serve as key enablers of the digital thread—linking engineering, manufacturing, supply chain, and service functions through a common source of truth. By embedding Module Variants into the MBE framework, organizations can streamline product definition, enhance cross-functional collaboration, and improve decision-making throughout the product lifecycle. Jakob will share how this approach is being implemented in practice, and how it supports a robust MBE implementation across business functions.
