Systems Engineering Challenges
• Propagate engineering information throughout the entire product life cycle
• Integrate knowledge from all internal stakeholders into the product development
• Increase the product maturity level at delivery time
• Increase the level of automation for mechanical, repetitive activities
• Anticipate defect detection during development

Our vision relies on models
Not only Model-based design, but Model-Based Development:
• Requirements specification / validation
• Design specification / verification
• Software development (requirements, design and V&V)
• Testing (enforcing test automation)
• Safety assessment
• Integration with CAE/CAD design
