The Development of SysML

SysML – An Enabler and a Threat?
IC-MBSE 2010
SysML as an Enabler
• A visual modeling
language with
semantics and
standard notation
• Communication
alignment with
software domain
SysML as a Threat
• MBSE ≠ SysML
• Complexity of
representation
• Rate of incorrect
implementation
(SysML treated as a
series of diagrams)
• “SysML as a universal
and complete
representation”

Changes in the Systems Domain
IC-MBSE 2010
• The SE domain
• COTS, GOTS, and reuse – increased emphasis on integration
and reconfiguration for new capabilities
• Intelligent, adaptive (self-evolving), and chaotic systems
• Widely divergent system lifetimes (cell phones and submarines)
• Compressed cycle time / accelerated time to market
• Dominance of commercial systems
• An era of evolution
• Influences of new technologies (biotech, …)
• Rise of cost-effectiveness (limited government budgets, market
economics in commercial domain)
• Rise of national specialization
• The noteworthy challenges of this generation are
systems problems
