PREEvision

Accelerate Model-Based Systems Engineering in One Shared Platform
Explore the Demo

Connect requirements, architecture, hardware, software, and validation in one future-proof platform. Keep complex system development consistent. With PREEvision, you work in one shared model, connect information across disciplines, and maintain traceability from requirements to implementation and test artifacts. Reduce rework, shorten alignment loops, and justify decisions with confidence.

As a decision-maker, you establish a consistent backbone for governance, compliance, and coordination across teams and suppliers. In your day-to-day projects, you rely on integrated workflows and a data model that stays usable from early definition to detailed design and change impact analysis. Build momentum for your engineering teams.

The Foundation for Innovation

PREEvision is your model-based systems engineering platform. It supports the RFLP approach by connecting requirements (R), functional and logical architecture (F/L), and the physical implementation view (P) in one single environment. Build bidirectional traceability between all viewpoints at any time, without breaking your workflow.

Widely used for electrical and electronic system development in automotive programs, PREEvision supports workflows from architecture design to wiring harness development. Vector brings PREEvision to additional industries where teams demand cross-domain collaboration and consistent engineering information in increasingly software-defined and connected environments.

Master Complexity with RFLP

PREEvision supports RFLP in one shared model. Intelligent links keep requirements, architecture, implementation, and verification connected as your system evolves.

  • R – Requirements Viewpoint
    Capture and refine stakeholder, system, software, and hardware requirements. Connect them bidirectionally to all development artifacts for complete transparency and precise change impact analysis.
  • F/L – Functional and Logical Architecture Viewpoints
    Describe system behavior and structure. Keep it seamlessly linked to requirements and the implementation view.
  • P – Physical Implementation Viewpoint
    View Model the realization of your system, including hardware and software. Keep it connected back to requirements and architecture to ensure real-time performance and reliability.

Designed for the Future

Rely on PREEvision when you need one consistent system model for your teams and stakeholders. It supports systems engineering that remains comprehensible and traceable across the entire lifecycle of software-defined systems. Future-proof your development process.
