Systems Engineering
For Software-Defined Systems
Model-Based Development That Masters Complexity
Modern technical systems are highly networked, multidisciplinary, and software-driven. Requirements, functions, architectures, software, hardware, tests, cybersecurity, and regulations exist in a tight web of dependencies. Fragmented tool landscapes fail to capture this reality.
Conquer this complexity with a holistic approach to model-based systems engineering (MBSE). Vector provides the integrated end-to-end development environment you need to design, secure, and evolve cyber-physical and software-defined systems across their entire lifecycle. Build the future with confidence, create momentum in your development cycles, and replace isolated artifacts with a single source of truth.
The Vector Perspective: Pragmatic Model-Based Systems Engineering


At Vector, we view systems engineering not as an abstract methodology, but as a pragmatic engineering discipline. The focus is never on a single product, document, or tool. The focus is on the system as a dynamic interplay of many elements and disciplines.
Our goal is to structure complex systems so they remain understandable, controllable, and future-proof, even when boundary conditions, requirements, or technical solutions change rapidly. We navigate the tension between order and complexity to deliver excellence.
- Structure instead of fragmentation.
- Connection instead of isolated artifacts.
- Transparency instead of a black box.
- Control instead of uncertainty.
How PREEvision Empowers Your MBSE Teams


PREEvision is the central platform that translates our holistic understanding of systems engineering into a model-based reality. The fundamental concept is simple yet rigorous: All relevant information about a system lives in one shared, consistent system model.
This model maps different perspectives of the exact same system, providing full support for the RFLP methodology. Information exists exactly once and is viewed from different angles depending on the role, task, or question at hand.


RFLP Brought to Life
Navigate your architecture seamlessly across these integrated layers:
- Requirements and overarching goals.
- Functional relationships and networks.
- Logical system structures.
- Physical realizations in modular software stacks and hardware.
- Tests and continuous validation.
Our MBSE Solution, Your Benefits:
Master Complexity. Ensure Traceability.
Moving away from classic engineering landscapes with specialized, disconnected tools creates immediate qualitative advantages for your organization. The PREEvision approach ensures that relationships emerge through explicit connections in the system model, not through static documentation. Changes become an integral part of your workflow, not disruptive exceptions.
Manageable Complexity
Do not oversimplify your systems. Structure them. PREEvision keeps different architectural levels distinct while preserving the context of the entire system.
Unbroken Traceability
Lack of traceability slows down innovation. PREEvision links requirements, architectures, implementations, and tests directly. When you make a change, the impact becomes visible instantly, systematically, and consistently.
Orientation in Dynamic Projects
Team members always see the perspective relevant to their specific tasks while keeping the big picture in sight. This drives real-time performance and team spirit across global engineering hubs.
A Common System Understanding
Systems engineering becomes the unifying language between different disciplines, teams, and organizational units. Break down silos and foster true integration.
Sustainable Decision-Making
Decisions are not just made; they are anchored deeply within the system model. This makes every engineering choice explainable, transparent, and viable for the long term.
Key Capabilities of the PREEvision MBSE Toolset
Accelerate development and ensure quality with a scalable MBSE toolset designed to future-proof your systems.
- SysML-Based Diagrams: Model and visualize interactions visually using industry-standard notations, including sequence and activity diagrams.
