High-quality requirements in Model-Based Systems Engineering

Model-Based (MBSE) is the current trend in regard to Systems Engineering, leveraging testing and simulation activities. However, it’s also clear that textual requirements will remain in the scene since they are also key for testing, certification, and communication with other stakeholders.

This Webinar describes a real scenario where, while working in a model-based project using Rhapsody, there is the need of writing high quality requirements concerning the UML/SysML elements of the project.

In this scenario where UML/SysML models coexist with requirements, a crucial role is played by physical models simulations, indeed requirements feasibility is going to be tested against physical models simulation (FMUs files).
