 Hi Michael,

Depending on what you're trying to do, you may also find that design manager is sufficient.  Both rhapsody and rsa are UML base Modeling tools, which design manager supports.  However design manager can also be deployed standalone, to provide sketching, writing design documents and capturing architectural decisions in the web.  So if you don't want too much formality, design manager may be sufficient in itself.

There is a lot of overlap between rsa and rhapsody, but in general we tend to position rsa to it/business systems software developers who are normally developing in java or .net, whilst rhapsody is normally a better fit for systems developers (think sysml), embedded software and C++.

Both products integrate with design manager for either managing the UML models, or via an upload mechanism.

I hope this helps, but feel free to reach out to me on email if you've got questions.

Hi Michael,
Take a look at Rational Rhapsody. It is a visual modeling tool for systems and software designers. You can do structural and behavioral modeling with it and generate code. Code generation is key because you can test your application prior to deployment. It supports multiple languages - C, C++, Java, Ada, C#. It links to the requirements management tools so you can set up traceability between requirements and model elements.  This way you refine and validate your requirements earlier in the process. You can also hand-off your architectural design to the coding team to implement and test.

Thanks.  Is Rhapsody integrated with the Jazz platform and RRC, RQM, and RTC?

Also, how would Rational Software Architect (RSA) compare with your summary of Rhapsody?
