From Models to Decisions - Why Modeling Must Become an Execution Engine in the Age of AI
Abstract
The role of modeling is undergoing a fundamental shift. Traditionally, models have been used to document, specify, and communicate complex systems. However, in an era increasingly shaped by artificial intelligence, distributed systems, and rapidly evolving requirements, this is no longer sufficient.
This keynote argues that modeling must evolve from a descriptive discipline into an execution-driven capability. Instead of creating models that merely represent systems, we need models that actively shape decisions, enable automation, and provide structure for AI-driven reasoning.
Drawing on real-world experience from enterprise architecture, model-based systems engineering (MBSE), and large-scale industrial deployments, this talk explores:
- Why traditional modeling approaches are losing relevance in modern engineering environments
- How AI changes the expectations towards structure, semantics, and traceability
- What it takes to turn models into actionable assets across the lifecycle
- How modeling can bridge the gap between engineering rigor and business impact
The keynote challenges the audience to rethink modeling not as an artifact, but as a strategic capability - one that enables organizations to manage complexity, increase resilience, and unlock the full potential of AI-assisted engineering.
