IBM Rhapsody v8.1.3 IBM® Rational® Rhapsody® Architect for Systems Engineers is an integrated, systems engineering environment for analyzing project requirements. It uses Systems Modeling Language (SysML) and Unified Modeling Language (UML) to enable rapid requirements analysis and visual, model-based design. Rational Rhapsody Architect for System Engineers helps systems engineering teams design complex functionality in less time. Requirements analysis—uses SysML and UML to help you analyze requirements, perform trade studies with parametric constraint evaluator and design structural and behavioral aspects. Requirements traceability—link requirements to design elements and test cases to help ensure coverage and assess impact of change Team collaboration—helps teams collaborate to manage the complexity of developing consistent designs across different environments. Visual development—graphically captures designs using industry-standard SysML and UML, or Domain Specific Languages (DSL) such as AUTOSAR. Lifecycle support and add-on software—integrates with other IBM Rational products for full product lifecycle development including OSLC integration through Rational Rhapsody Design Manager. Plus, you can extend the functionality of Rational Rhapsody Architect for System Engineers with optional add-on software
