Find answers to the most common questions about Model-Based Systems Engineering (MBSE), MBSE as a Service, Cameo Systems Modeler, SysML, and how VETS can support your digital engineering program.
What is MBSE (Model-Based Systems Engineering)?
Model-Based Systems Engineering (MBSE) is a formalized methodology that promotes the use of models as the primary means of information exchange, rather than document-centric approaches. MBSE uses formal modeling languages like SysML (Systems Modeling Language) to capture system requirements, structure, behavior, and interconnections in an integrated, executable model. MBSE reduces errors, improves traceability, and supports better decision-making across the system lifecycle.
What is MBSE as a Service (MBSEaaS)?
MBSE as a Service (MBSEaaS) is a managed service model where organizations access expert MBSE capability, tools, and practitioners on demand — without building a full in-house team. VETS offers MBSE as a Service to defense, aerospace, and government customers, providing SysML modeling, Cameo administration, model governance, and MBSE training as a subscription or task-order service. This reduces startup costs and accelerates time-to-capability.
What is Cameo Systems Modeler?
Cameo Systems Modeler (formerly known as MagicDraw with the SysML plugin) is a leading MBSE modeling tool developed by Dassault Systèmes (formerly No Magic). It is widely used across the Department of Defense, aerospace industry, and NASA for creating SysML models, DoDAF architecture views, and UAF frameworks. VETS specializes in Cameo Systems Modeler configuration, administration, training, and expert SysML modeling using this tool.
What is SysML?
SysML (Systems Modeling Language) is a general-purpose architecture modeling language for systems engineering applications. It is a profile of UML (Unified Modeling Language) standardized by the Object Management Group (OMG). SysML supports the specification, analysis, design, and verification of complex systems. It provides nine diagram types: block definition diagrams, internal block diagrams, parametric diagrams, activity diagrams, sequence diagrams, state machine diagrams, use case diagrams, requirement diagrams, and package diagrams. SysML v2 is the next-generation version currently being adopted. VETS has expertise in both SysML v1 and SysML v2.
Who are No Magic and what is their relationship to Cameo?
No Magic was the original developer of MagicDraw and the Cameo suite of MBSE tools. No Magic was acquired by Dassault Systèmes, which now markets Cameo Systems Modeler, Cameo Enterprise Architecture, and related products under the Dassault Systèmes brand. VETS has been working with No Magic tools since their inception and maintains deep expertise in the full Cameo/MagicDraw product line.
What MBSE services does VETS offer?
VETS offers a comprehensive range of MBSE services including: MBSE as a Service (MBSEaaS), SysML model development and architecture, Cameo Systems Modeler administration and configuration, MBSE methodology implementation (INCOSE, OOSEM), DoDAF and UAF architecture framework development, Digital Twin development, Digital Thread integration, MBSE tool integration (Cameo with DOORS NG, Teamcenter, JAMA), MBSE training and workforce development, and independent model reviews and governance. VETS serves as a trusted MBSE partner for DoD programs, defense primes, and aerospace organizations.
What is the difference between MBSE and traditional systems engineering?
Traditional systems engineering relies primarily on documents (Word, PDF, spreadsheets) to capture and communicate system information. MBSE replaces or supplements these documents with a centralized, consistent model that serves as the authoritative source of truth. MBSE enables automated consistency checking, requirement traceability, and model-based analysis — capabilities that document-based approaches cannot efficiently provide. The DoD Digital Engineering Strategy mandates the adoption of MBSE across defense acquisition programs.
Does VETS support DoD Digital Engineering Strategy?
Yes. VETS is deeply aligned with the DoD Digital Engineering Strategy, which mandates the use of authoritative sources of truth, MBSE, and digital engineering practices across DoD acquisition programs. Our team helps defense programs implement the five strategic goals of the DoD DE Strategy: formalize digital engineering approaches, provide a digital engineering ecosystem, transform practices, cultivate supporting infrastructure, and connect the engineering enterprise.
What is Teamwork Cloud (TWC) and how does VETS support it?
Teamwork Cloud (TWC) is the server-based collaboration platform for Cameo Systems Modeler, enabling multiple engineers to work on SysML models simultaneously in a version-controlled environment. VETS provides Teamwork Cloud installation, configuration, administration, user training, and integration with other enterprise tools like IBM DOORS NG and Teamcenter.
How do I get started with MBSE at my organization?
Getting started with MBSE typically involves: assessing your current systems engineering maturity, selecting an MBSE methodology and toolset (such as Cameo/SysML), piloting MBSE on a representative project, and scaling across programs. VETS offers MBSE readiness assessments, pilot program support, and full MBSE as a Service engagements to help organizations at any stage of their MBSE journey.

Is VETS an SDVOSB?
Yes. VETS is a certified Service-Disabled Veteran-Owned Small Business (SDVOSB). This certification enables sole-source and set-aside contracting opportunities with the Department of Defense and other federal agencies. VETS personnel hold active security clearances and are experienced in supporting classified and sensitive defense programs.
