#1 about 5 min

Introduction to speakers and model-based systems engineering goals

An overview of the presentation's focus on adopting model-centric techniques for modern safety-critical systems development.

#2 about 2 min

Adopting systems engineering across a large enterprise

How large automotive organizations unify complex functional pipelines requiring integrated architecture, methods, and tooling.

#3 about 1 min

Integrating development processes and realization methods

A layered approach to aligning business roadmaps, core methodological flows, and practical tooling usage.

#4 about 2 min

Architecting a speed indicator with functional requirements

Translating functional and non-functional requirements into a logical technical design with complete traceability.

#5 about 2 min

Preventing software architecture deterioration over product lifespans

Maintaining dedicated architectural oversight prevents escalating maintenance costs and continuous integration delays.

#6 about 4 min

Replacing document-centric workflows with model-based systems engineering

Meeting mandatory regulatory standards for automated driving by adopting traceable, centralized modeling over disconnected documents.

#7 about 4 min

Utilizing trace links and graphs for safety-critical modeling

Modeling behavior with graphs and trace links transforms static architectures into fully analyzed machine-readable data structures.

#8 about 4 min

Structuring architecture with diagrams and containment trees

Representing cyber-physical architectures via block diagrams and activity flows organized systematically in relational trees.

#9 about 2 min

Applying git workflows for agile model iteration

Achieving concurrent engineering and regulatory compliance by treating models like standard software code repositories.

#10 about 4 min

Managing product variability using intelligent branching strategies

Decoupling complex product variations into independent branches rather than maintaining monolithic baseline configurations.

#11 about 4 min

Enabling agile team collaboration with specialized visual merging

Resolving structural discrepancies using visual tools that compare diagrams and element trees during parallel development.

#12 about 4 min

Bringing continuous integration and package management to models

Transitioning traditional modeling environments into modern engineering ecosystems utilizing automated pull requests and reusable components.
