Modeling, systems engineering
Cloud-native, web-based modeling for systems engineering teams that build complex, connected products.
Rhapsody SEIBM Rhapsody Systems Engineering (Rhapsody SE) is IBM’s web-based, cloud-native tool for model-based systems engineering in SysML v2. Systems engineers design, analyze and coordinate complex products in the browser, together and in real time.
SysML v2 captures requirements, constraints and relationships more precisely than SysML v1, with a textual and a graphical notation. SysML v1 models from Rhapsody can be reused and migrated.
Rhapsody SE links to IBM Engineering Requirements Management DOORS Next, IBM Engineering Test Management and IBM Engineering Workflow Management through OSLC, and exposes the SysML v2 API for model-based integrations.
SysML v2 uses layers of abstraction for large systems. Global configurations keep models, requirements and tests on the same baseline, and Harmony and HarmonyIQ add process accelerators, model checkers and model-aware guidance.
Release 1.8 adds a Model Context Protocol (MCP) API, so AI agents can analyze architecture, behavior and change impact across models. Rhapsody SE runs as IBM SaaS or on premises, including air-gapped environments from 1.8.

SysML v2 is the next version of the OMG systems modeling language, with a precise textual and graphical notation and a standard API. Rhapsody SE has been generally available since 2024; release 1.8 (July 2026) adds reporting, AI analysis and scale features.
Rhapsody SE is cloud-native. IBM SaaS removes servers entirely; on-premises installation, including air-gapped environments from 1.8, keeps data inside your network.
Yes. Rhapsody SE reuses SysML v1 models and supports migration to SysML v2. We start with one model as a pilot and check the result with your engineers.
Through OSLC links, with global configurations keeping models, requirements and tests on the same baseline.
Release 1.8 adds a Model Context Protocol (MCP) API, so AI agents can analyze architecture, behavior, compliance and change impact across models. HarmonyIQ gives model-aware process guidance.
For code generation, executable simulation, UML and AUTOSAR, yes. Many teams use Rhapsody SE for systems engineering and Rhapsody for software design.
