Using mobile devices for collaborative requirements engineering

Abstract

In requirements engineering, CRC modeling and use case analysis are established techniques and are often performed as a group work activity. In particular, role play is used to involve different stakeholders into the use case analysis. To support this kind of co-located collaboration we developed CREW-Space, which allows several users to simultaneously interact through Android-enabled mobile devices with the same model displayed on a shared screen. Furthermore, it keeps track of the current state of the role play and, in addition, each mobile device serves as a private workspace; it actually turns into a tangible digital CRC card.
