Model Based System Engineering with SysML

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 course provides a solid grounding in MBSE project processes and how to build robust model using SysML notation and diagrams. Attendees will receive solid grounding in MBSE and SysML with the understanding and confidence to participate, and be successful as a modern-day system engineer.

Objectives:

• Explain the six goals of Model Based System Engineering
• Transition through the four pillars of MBSE from Requirements to Structure to Behavior to Parametrics
• Create and relate all 9 SysML diagrams with understanding of the underlying model
• Structure the model for testing, validation and requirements satisfaction

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.

In this course, you will learn how to:

• Explain the six goals of Model Based System Engineering
• Transition through the four pillars of MBSE from Requirements to Structure to Behavior to Parametrics
• Create and relate all 9 SysML diagrams with an understanding of the underlying model
• Structure the model for testing, validation and requirements satisfaction
• Leverage continued support with after-course one-on-one instructor coaching and computing sandbox
