- [Instructor] SysML offers a comprehensive set of modeling constructs that we can use to build different types of models. Let us look at a few key constructs that set the foundation for a modeling project. Requirement modeling starts with the stakeholder needs and captures them as constraints and calculations to express what the system should do. As we specify the requirements, we start working on structural modeling alongside. Structural modeling focuses on the composition of the system in terms of items, parts, ports, connections, and allocations. It represents how system parts are decomposed, interconnected, and classified. Behavioral modeling builds upon the elements modeled in the structural model and focuses on the flow of messages, actions, and states of the system and its parts. As the structural and behavioral models evolve, we can further refine and elaborate the requirements as cases that are calculations or steps to achieve the objectives defined in the requirements.
