What is model-based systems engineering, or MBSE?
Model-based systems engineering (MBSE) is the structured use of visual models to represent system requirements, architecture, design, and behavior throughout the development lifecycle using specific languages and tools, and is a cost-effective way to explore and document system characteristics. Early testing and validation through modeling enables swift feedback and updates on requirements and design decisions while significantly reducing or eliminating dependence on traditional documents.
Future work on DOD programs will require transfer of data across the engineering enterprise using MBSE models. Mercury Systems has invested in and institutionalized MBSE across functions to meet this fast-approaching requirement.

Accelerate Engineering Cycles
MBSE creates visibility among connected systems through a “digital thread.” This enables real-time collaboration using authoritative sources of truth, automated generation of documentation, reuse of proven engineering, and faster integration of system changes. All of which significantly cuts development time, speeding overall engineering cycles.
Complement Traditional Engineering Processes
Sound systems engineering processes can benefit immensely from MBSE. When used in conjunction with traditional engineering practices, MBSE provides numerous benefits from greater cost efficiency to improved product quality. Using SysML and the right modeling software, engineering teams can develop clear and precise descriptions of system behavior and structure, removing the ambiguity common with older tools and methods.
Reduce Technical and Programmatic Risk
The use of MBSE breaks down the silos that typically exist among different engineering disciplines. The models facilitate early collaboration, stakeholder feedback, and change impacts around a common understanding of the system being developed. In addition, the reuse of validated designs reduces the risk of development issues and schedule delays while improving cost estimates and system assurance.
Model-Based Systems Engineering (MBSE) offers significant advantages in the design and management of complex systems. By leveraging detailed models, MBSE enhances the understanding and communication of system requirements, functionality, and performance among stakeholders, ensuring more effective system design. This approach allows for early detection of design issues, reducing the risk of costly errors and rework. Additionally, MBSE facilitates better traceability and integration of system components, ensuring that all parts work harmoniously. The ability to simulate and validate complex systems in a virtual environment also leads to more efficient and reliable system development, ultimately improving overall project outcomes.
The process of Model-Based Systems Engineering (MBSE) begins with the comprehensive capture of system requirements, ensuring a clear and shared understanding of stakeholder needs. Following this, a high-level system architecture is developed, defining the key components and their interactions. Detailed models of these components are created using specialized MBSE tools, allowing for in-depth analysis and simulation. These models are continuously validated and verified to ensure they meet the specified requirements. Throughout the process, MBSE emphasizes traceability, enabling effective change management and alignment of all system aspects with project goals. The final step involves generating detailed design documentation from the models, which supports implementation and integration, ensuring a smooth transition from design to deployment.
