US2StarTool: Generating i* Models from User Stories

Abstract

In agile methods, the requirements are represented by user stories. However, this model does not allow a good visualization of context in which a story is inserted, reducing the understanding of the system as a whole. On the other hand, the i* model presents dependencies among organizational actors, and the understanding of the context in which a requirement is inserted. This paper presents an implementation of an automated solution as a tool to mapping user stories into i* models, US2StarTool, adding a support for agile develop- ment environment. US2StarTool can help requirements engineer in agile devel- opment environments contextualizing the environment in which user stories are inserted and showing relationships between the actors and the system.
