Barres Systems Engineering is a specialized consulting firm focused on supporting complex government acquisition programs.

Areas of Expertise

  • MBSE-Driven Requirements Engineering

    We help clients implement responsive, model-based systems engineering frameworks that integrate geotechnical, environmental, and accident-based inputs into architecture and requirements decomposition activities.

  • System-Level Verification Planning and Execution

    Traditional civilian reactor programs—governed by the NRC—focus primarily on safety through design basis accident (DBA) analysis. However, the DoD5000 process requires more granular and systematic verification of performance, functionality, and interface compliance across all architecture levels: system, segment, element, and sub-system. Our team brings extensive experience in developing tailored verification strategies using a combination of test, analysis, demonstration, and examination methods to ensure coverage, traceability, and review readiness in accordance with military standards.

  • Cyber, Nuclear Surety, and Survivability Integration

    Our team has supported certification activities across multiple defense platforms, ensuring early and continuous compliance with mission assurance, cybersecurity (e.g., NIST 800-171 Rev. 2), and nuclear surety requirements.

  • System-Level Trades and Risk Analysis

    We lead cost–capability trade studies that inform achievable system baselines aligned with customer intent, budget constraints, and mission-driven performance objectives—essential for avoiding "design dead-ends" in the face of cross-domain constraints such as modularity, transportability, and manned-only operations.
