Capsules enable your team to design real-time embedded systems the way they really operate.

Productivity Depends on Clear Communication Real-time embedded systems often require Integrated symbolic large-scale development teams to handle the debugging on host and complexities of design and construction. target Without good communication and the clear st capture of system architecture, developing in such an environment can be disastrous. Rational Rose RealTime can help you avoid such pitfalls.

• Improve communication between all members of your team through the power of the UML.

• Integration between Rational Rose RealTime and Rational Requisite Pro® ensures that no requirements get lost in translation from requirements to design.
