Smarter Systems. Stronger Missions.

Model-Based Systems Engineering

A disciplined digital engineering approach that strengthens system integrity, accelerates development, and delivers traceable, defensible decisions across the entire lifecycle.

Rising system complexity, software-driven architectures, and rapid modernization cycles demand engineering approaches that go beyond traditional documents. Programs need authoritative, interconnected models that reveal impacts earlier, increase traceability, and maintain alignment across distributed teams and disciplines.

MBSE provides that foundation. By shifting from static documents to a structured, architecture-driven modeling environment, organizations gain clearer insight, stronger requirements discipline, and a development process that is both faster and more resilient. MBSE reduces ambiguity, exposes integration risks early, and ensures that engineering decisions remain grounded in accurate, verifiable data.

AWESUM® extends MBSE into a unified lifecycle that streamlines certification and ensures aviation systems are reliable, compliant, and mission-ready.

Our MBSE
Approach

Precise Systems applies MBSE as a unified digital framework that connects requirements, architecture, behavior, interfaces, and verification into a single, coherent engineering environment. Our approach is rooted in repeatable methodologies, standards-based modeling practices, and the integration of advanced tools that support enterprise-scale engineering.

Our MBSE solutions enable:

  • A centralized model that serves as the authoritative technical baseline.
  • Complete lifecycle traceability across requirements, architecture, and verification.
  • Multi-domain alignment between hardware, software, and system-of-systems teams.
  • Early identification of integration risks and design issues through model-based analysis.
  • Consistent modeling practices using reference architectures and structured methodologies.
  • Cloud-enabled collaboration environments and common data languages that support distributed teams.

By applying MBSE as a foundational engineering discipline, we help organizations reduce rework, accelerate decision cycles, and maintain alignment from concept through sustainment.

MBSE Capabilities

Our MBSE practitioners bring deep technical expertise across digital engineering, modeling, and lifecycle integration.

Capabilities include:

  • Requirements Engineering: Model-based capture, decomposition, allocation, and validation to ensure mission-aligned technical clarity.
  • Architecture and Interface Modeling: Structured modeling of system functions, components, interfaces, and behavioral flows that improves integration quality.
  • Configuration and Change Management: Model-centric baselines that maintain consistency, manage change impact, and ensure disciplined evolution.
  • Risk Identification and Mitigation: Early discovery of architectural gaps, performance constraints, and integration risks through model-based analysis.
  • Model-Based Test and Evaluation: Virtual verification, behavioral simulation, and early test alignment grounded in authoritative model data.
  • Lifecycle Planning and Program Management: Digital engineering artifacts that support better planning, cost analysis, schedule management, and milestone execution.

The Precise Difference

A Unified Lifecycle Suite
AWESUM® fuses modeling, simulation, MOSA, and certification into one environment, accelerating development, reducing risk, and ensuring compliance.

Lifecycle Modules

  • Develop – Rapid, traceable design
  • Verify – Robust testing and results management
  • Qualify – Automated DO-178C documentation
  • Simulate – Digital validation of system needs
  • FAME – FACE™-based model development

Why It Stands Out
Mission-tailored, not one-size-fits-all. AWESUM embeds MBSE into every step, delivering faster, safer, and more reliable outcomes.
