We investigate how stories can be used in system analysis and design to better understand the application domains. The research question we explore is: How can we employ narratives as a complement to use cases to improve our understanding of application domains? To examine this question, we study the effects—i.e., recall and problem solving—of supplementing a use case with a user story. We focus on two features of stories that can facilitate comprehension, concrete thematic content and causal explanatory information.
