Custom Tool or Standard?

Decision guidance from 20 years of project experience: when a custom DSL pays off, when a UML/SysML profile is the better choice, and how to get from domain analysis to a productive tool.

  • Structured decision framework: DSL vs. UML/SysML profile vs. tool extension — with two real cases where itemis advised against a new DSL
  • Four sources of lasting value: early validation, end-to-end automation, secured expert knowledge, vendor independence
  • The itemis approach from workshop and live prototype to integration and maintenance
  • How AI is changing what is feasible within a given budget
