Tool Support

  • Harmony-SE (and Harmony) were created as tool- and vendor-neutral, model-based methodologies. No process framework tool exists from IBM Rational/Telelogic or third-party provider.
  • Tool support for MBSE that supports the methods specified by Harmony-SE and Harmony is, of course, provided by IBM Rational/Telelogic via the Tau and Rhapsody product offerings.


  • Harmony-SE/SysML Deskbook has been published to help guide the systems engineer and project manager through the entire MBSE methodology. In addition, IBM Rational/Telelogic offers professional services to support methodology adoption.
