MBSE‑Native Requirements Engineering

Built for Connected Systems Engineering

Traditional documents do not understand your system. When requirements change in isolated text files, important context and engineering consequences are lost. Connect requirements, architecture, and verification in a single, integrated model.

PREEvision embeds requirements engineering directly into your MBSE workflow. Instantly see the impact of every change, maintain unbroken traceability, and confidently drive decisions across your entire engineering process – without ever switching between disconnected tools.

Beyond Document-Based Requirements

PREEvision solves the traceability challenge by embedding requirements directly within the system model. You link them bidirectionally to functional architectures, logical designs, software, hardware, and test artifacts.

This ensures that every engineering decision connects to a specific stakeholder need. You can start with familiar requirements engineering workflows and scale into full model-based systems engineering exactly when and where it delivers real value.

The requirements, functional, logical, and physical (RFLP) viewpoints in PREEvision.

Rigorous Architectural Control

Change Impact in Context: Instantly visualize exactly what is affected across all RFLP layers when a requirement changes.
Seamless Integration: Exchange requirements effortlessly with customers and suppliers using ReqIF, Excel, and other standard formats.
Consistent System Model: Keep global teams and projects perfectly aligned with a single source of truth.
Scalable Adoption: Maintain strong, bidirectional links without the need for a massive, day-one MBSE rollout.

Securing Intent: A Series on Future-Proof Architecture in Requirements Engineering

You build complex systems to solve the challenges of tomorrow. Yet, as projects evolve from initial requirements to final delivery, the original design intent often fades quietly. In this mini-series, we explore the state-of-play in contemporary requirements engineering from a real engineer's perspective. We examine the hidden friction of disconnected toolchains and challenge the common belief that a single, unified tool is the ultimate answer. Dive into the series to discover practical insights on how to protect your intent, eliminate data silos, and drive excellence through seamless integration.

Enterprise-Grade Requirements Management

PREEvision provides all the robust tools you need for classic requirements management, supercharged by the underlying model:

Life Cycle & Versioning: Track requirements through freely designable life cycles. Check-in/check-out versioning ensures every change remains traceable over time.
Reviews & Votings: Collaborate seamlessly. Set up agreement projects, assign stakeholders, and use dedicated chat views to review and approve requirements directly in the tool.

Systematic Reuse: Avoid redundant work. Reuse requirements and functions across different projects to accelerate development and manage complexity.
Automated Specifications: Generate dynamic reports and system specifications automatically. Placeholders ensure your documents always reflect the current state of the model.

RFLP-Centric Development With PREEvision

Experience requirements engineering in action. This tutorial from the PREEvision MBSE Trial shows you exactly how to capture needs and connect them to your system architecture within the RFLP framework.

We offer PREEvision as a hosted trial, giving you the opportunity to explore its capabilities hands-on. Interact directly with our demo model and experiment with MBSE in a real-world context.
