—George E. P. Box
Since humans began engineering systems and structures, they have used models to abstract, learn, and communicate. Model-Based Systems Engineering (MBSE) is the application of modeling of requirements, design, analysis, and verification activities as a cost-effective way to learn about system characteristics prior to construction. Models provide early feedback on system decisions and communicate intended aspects of the system to all involved, including Customers, stakeholders, developers, testers, etc.
