The role of user scenarios as the central piece of the development jigsaw puzzle

This paper considers the employment of user scenarios within the context of the prototypical development ofa mobile learning architecture. Through a case study, it demonstates how scenarios have influenced the development process by focusing on the role of teachers and learners throughout different stages of the prototype development. It illustrates ways in which scenarios relate to system requirements and evaluation, and how they offer a communication strand between technical and non-technical partners. During the project, key scenarios were identified and gradually refined to become more concrete, so that eventually they could be used to evaluate the final system. Scenarios used in this way also serve to resolve the difficulty identified by Taylor (2003) of how to bring together a high-level evaluation design with implementation issues
