Background of SysML — Lesson 1

This lesson covers the concept of Model-Based Systems Engineering (MBSE) and its contrast with document-based approaches. It explains how MBSE captures system information in a model, which is managed throughout the system's lifecycle. The lesson also discusses the future of MBSE, including its expansion across the entire lifecycle and all levels of design. It highlights the importance of complementing MBSE with agile system development practices and leveraging modeling patterns. The lesson further delves into SysML, a general-purpose modeling language used in MBSE, and the role of a system model in managing complexity and risk, enforcing rigor, and providing a consistent definition for system development.
