SysML – An Enabler and a Threat?

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”

Research and innovation vehicles• Organic MBSE Community / Working Groups• Masters and Doctoral students (growth in SE programs)• Systems Engineering Research Center (SERC)• DARPA META program

IC-MBSE 2010

Changes in the Systems Domain

• 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
