Andreas Winters
Last position:
Enterprise Architect at Own development / IP of CAMCO Engineering UG
UEF 3.0 · Semantic Government Overlay (SGO) · Autonomous Systems (UAS / dual use)
- Designed: Semantic Government Overlay (SGO) – AI-guided administration without replacing existing specialist procedures. Read-only semantic layer over registers and specialist processes based on the Federal Information Management (FIM). Decision authority remains with the case worker (architecture principle).
- Developed: Reference architecture with source-backed, derived statements (Executable Ontologies OWL/RDF/SHACL). Technically guaranteed purpose limitation and no-write-path principle in specialist data – auditable, without a central data pool.
- Anchored: Regulation as a design principle: EU AI Act (high-risk obligations for public-sector AI, fundamental rights impact assessment under Art. 27), GDPR, NIS2, and administrative automation limits (§ 35a VwVfG, § 31a SGB X) as technical control points in the architecture.
- Created: Methodical tool for pilot organizations: data pipeline assessment (phase 0), compliance blueprint, and management summary as a decision-ready package for public administration.
- Specified: UEF 3.0 as a successor architecture to TOGAF – decision paper, canonical ontology, six-layer architecture, read/actuate boundary, federation registry, terminology concordance, and release delta as a closed specification status.
- Architected: AI-native mission OS for autonomous UAS and ground robotics as a tactical layer on top of a separately approved autopilot. Run-time assurance according to ASTM F3269-21 (Simplex pattern): the verified safety controller keeps authority, the AI function provides suggestions.
- Designed: Three-tier architecture – Tier 0 autopilot with 650 Hz flight control on RTOS, Tier 1 AI OS with semantic world model and multi-agent cluster, Tier 2 swarm and ground mesh. Zenoh as the primary fabric, MAVLink as the only authenticated command path (single writer). Result: graceful degradation – loss of the mission, not of the aircraft.
- Secured: Two-gate chain on the read/actuate boundary – governance gate (can-question: AI Act risk class per actuation, enforced human oversight under Art. 14, immutable log) before the RTA safety monitor (is-it-correct question: flight envelope, geofence, energy reserve) with revert to the baseline controller.
- Anchored: Dual-use architecture with common core and build-time fork instead of runtime switch. Three separate legal levels: civil variant – UAS under the EASA Basic Regulation (EU) 2018/1139 with the limited applicability under Art. 2(2) of the AI Act, ground robotics under the Machinery Regulation 2023/1230 with the full high-risk obligation chain, Cyber Resilience Act for both; unarmed carrier variant as defense material under AWG/AWV and Dual-Use Regulation 2021/821 (BAFA approval); armed variant under KrWaffKontrG. Each variant lives under exactly one dominant legal regime. Evidence base: AI BOM, SBOM, and complete data lineage.
- Analyzed: System analysis and realignment of grown engineering system landscapes. Approach concept for consolidation without migration – semantic layer over the existing sources instead of data transfer. Result: decision-ready implementation concept including an evaluation model for the target architecture.

About the technology
System view
Model-Based Systems Engineering, often called MBSE, replaces scattered documents with connected models of a system. It helps teams define requirements, behavior, interfaces, and architecture in one place. That makes it easier to align hardware, software, and operations before build work starts.
Typical work
- SysML models for requirements, structure, and behavior
- Interface definitions across subsystems
- Traceability from needs to verification cases
- Architecture views for reviews and decision-making
Strong specialists also support V&V planning, model reviews, and stakeholder workshops. In Germany, this is common in complex industrial programs where teams need disciplined coordination across sites and suppliers.
Tooling stack
MBSE work often centers on SysML and tools such as Cameo Systems Modeler, Capella, Enterprise Architect, or Rhapsody. Professionals also work with requirements tools, version control, simulation, and model exchange formats. The exact stack depends on whether the goal is analysis, documentation, or digital thread integration.
When to hire
Bring in freelance expertise when your current models are inconsistent, requirements lack traceability, or teams disagree on system boundaries. It also helps when a program is starting a new platform, moving from document-based engineering to MBSE, or needs temporary support for model setup and governance.
What strong experts do
Good specialists do more than draw diagrams. They define clean model structures, keep naming and relationships consistent, and connect requirements to architecture and tests. They also challenge vague inputs, ask the right questions early, and make trade-offs visible before they turn into rework.
Where it fits
MBSE is used in aerospace, automotive, defense, rail, energy, and industrial equipment. It supports safety-related systems, embedded platforms, and products with many interfaces or variants. A strong freelancer can work remotely on model maintenance or on-site when workshops, reviews, or stakeholder alignment need direct contact.
Frequently asked questions
Key details about Model-Based Systems Engineering, drawn from the questions we get asked most.
Model-Based Systems Engineering is used to describe and manage complex systems through connected models instead of isolated documents. Teams use it for requirements, architecture, interfaces, behavior, and verification planning. It is especially useful when many specialists need a shared system view.
MBSE keeps relationships between requirements, functions, structure, and tests inside the model. Document-based work can still be useful, but it is easier for links to break and for versions to drift apart. MBSE gives teams a clearer traceability chain and a more consistent review process.
A strong Model-Based Systems Engineering specialist should know at least one major SysML-capable tool such as Cameo Systems Modeler, Capella, Enterprise Architect, or Rhapsody. Knowledge of requirements tools, model versioning, and exchange formats is also useful. The best fit depends on the client’s process and tool landscape.
A strong MBSE freelancer usually brings systems thinking, requirements engineering, architecture design, and verification planning. Depending on the project, knowledge of safety, embedded systems, or domain standards can matter too. Good communication is critical because the work sits between many specialist groups.
A Model-Based Systems Engineering project does not always need a large team, but it does need someone who has worked on real system complexity. Simple model cleanup can be done by a focused specialist, while new method setup or governance needs broader experience. The more interfaces and stakeholders you have, the more valuable that depth becomes.
Most MBSE tasks can be done remotely if the specialist has access to the model repository, tool environment, and key stakeholders. On-site time helps when teams need workshop facilitation, architecture alignment, or fast decisions across disciplines. Many clients use a mix of both.
Look for clear model structure, disciplined traceability, and the ability to explain why a model decision was made. A strong Model-Based Systems Engineering expert should show examples of requirements flow, interface management, and review support. You want someone who improves clarity, not someone who only builds diagrams.
No. MBSE is the method; SysML is one of the main languages used to express it. A good specialist understands both the modeling approach and how to apply the language to real system work. That distinction matters when a company is choosing tools, defining process, or training a team.
