Experts agree, the advantages of using Model-Based Systems Engineering (MBSE) with SysML are enormous, and include:
- Improved risk management
- Better requirements management
- Increased efficiency and cost savings
- Improved communication and collaboration
- Enhanced system understanding and documentation
- Improved system quality and performance
By testing and validating system characteristics early, models facilitate timely learning of properties and behaviors, enabling fast feedback on requirements and design decisions.
Clearly, models provide an efficient way to explore, update, and communicate system aspects to stakeholders while significantly reducing or eliminating dependence on traditional documents.
MBSE historically focused on expressing and recording requirements, design, analysis, and verification information. But as modeling technology matured, it provided even more value by accelerating learning (e.g., simulation) and providing better insights into the physical world (e.g., digital twins).
Experts in this area believe both are important to evolve live systems and enable Enterprise Solution Delivery.
Another benefit of MBSE: Risk due to technology is also reduced, because of a greater focus on formalizing how the technology works.
There has been a lot written of late about how the model-based design aspect of MBSE helps get design right the first time, reducing development costs and timescales, where the design is not simple for the designers.
Another MBSE benefit on the design side is the higher system reliability due to better integration of reliability considerations into design on a real-time basis (DFMEA).
There’s also the opportunity to better integrate design of the product with design of its maintenance system, for improved maintainability and reduced maintenance costs.
Of course, models are not a perfect representation of a system, they do provide knowledge and feedback sooner and more cost-effectively than implementation alone. And models allow the simulation of complex system and system-of-systems interactions with appropriate fidelity to accelerate learning.
In practice, engineers use models to gain knowledge and to serve as a guide for system implementation. In some cases, they use them to directly build the actual implementation (e.g., electrical CAD, mechanical CAD).
