Model Based System Engineering with SysML
Course 3682
3 DAY COURSE

Model Based System Engineering (MBSE) is a megatrend in modern software and systems engineering – the key element in larger engineering transformation initiatives. Model-based, not document-based, MBSE clarifies understanding and has been empirically proven to significantly accelerate development projects.

This 3-day Hands-On course provides a solid grounding in MBSE project processes and how to build robust models using SysML notation and diagrams. Attendees will receive a solid grounding in MBSE and SysML with the understanding and confidence to participate and be successful as modern-day system engineers.

The course case study evolves from concept to full model and is achieved through comprehensive hands-on exercises developed entirely by the attendee. Those attending can choose to use Dassault/Magic Draw/Cameo or Sparx Systems Enterprise Architect.
