Positioning of UML in V-Model

Relevance and Benefit for MBSE

Reasons from Industry (example):

  • Increase consistency and clearness of information by providing a common language and representation (Focusing E/E & SW)
  • Improve communication, collaboration & knowledge exchange efficiency across domains, business segments and organizations
  • Increase efficiency in system conception & specification
  • Support process automation in data exchange, by report and code generation
  • Industry standard modelling language for software engineering (ISO 19505)

Risks and Impediments

What happens if we do nothing:

  • Lack of tool interoperability, cross domain & cross enterprises
  • A industrialized consistent (automated) development toolchain from System (SysML) to Code (UML) can’t be achieved
  • Efficient cross enterprise SW Development is Tool Vendor specific
