What is Rhapsody - Designer for Systems Engineers?

IBM Engineering Systems Design Rhapsody - Designer for Systems Engineers uses Systems Modeling Language (SysML) and Unified Modeling Language (UML)—all within a MBSE (Model-Based Systems Engineering) environment. It helps you adapt to changing customer requirements, improves productivity and reduces time-to-market with advanced validation and simulation features.


Gain abstraction capabilities

Express specifications and design graphically. Improve communication across teams and across the supply chain by using industry standards and unambiguous notations.

Verify and validate

Get early and continuous proof of specification and testing of design through model-based simulation and analysis.

Provide traceability

Show how and why design decisions and trade-offs were made through the steps of requirements > specification > design > code.
