Rich-media scenarios for discovering requirements

Walking through scenarios is an effective technique for discovering requirements, but scenarios can differ widely in their abstraction levels and representation forms. Some requirements analysts use scenarios that describe a system´s external visible behavior. Others use live sequence charts to model a system´s dynamic behavior. Requirements analysts also use scenarios for everything from explaining a current system to walking through a future system´s behavior to discover its requirements. However, determining the right form of scenarios for different requirements tasks remains an open question -one we´re investigating with ART-SCENE. ART-SCENE is an Internet-based environment for generating and walking through text scenarios. The ART-SCENE tool supports rich media scenarios in requirement discovery. These scenarios help stakeholders recognize events that a system will have to handle.
