Model-based systems engineering (MBSE) utilizes formal modeling to enhance system design, requirements, and validation throughout development and lifecycle stages. MBSE and the Systems Modeling Language (SysML) provide a unified approach to manage requirements and facilitate collaboration among various stakeholders while allowing for early defect detection and exploration of multiple solutions. The document discusses the incremental implementation of digital threads in MBSE, its relevance across 12 industries, and outlines the objectives and audience for a course on MBSE.
