EventStudio provides constructs for sequence diagram based object modeling. It supports generation of message sequence charts (MSCs) and call flow diagrams used in telecom and embedded system development. When modeling with EventStudio, developers describe the interactions in the system in terms of a declarative modeling language. EventStudio then analyzes the model for design errors, inconsistent operations, resource leaks and invalid timer operations. Once the design issues have been addressed, it automatically generates sequence diagrams and collaboration diagrams.

EventStudio allows the developers to explore a large number of success and failure scenarios without individually documenting each scenario. The developers define a base scenario and then define other scenarios by specifying the differences with the base scenario. It manages the scenario definitions and generates the documents by merging the base scenario with the specified differences for each scenario.
