Interrelating Goal Models and Multimedia Scenes: An Empirical Investigation

Conceptual goal models are used to express intentional aspects of the system under development. Among others, goal models facilitate stake holder discussions and agreement about main system aspects during early requi rements engineering phases. As experiences from participatory design ind cates, the use of multimedia representations (especially videos) lead s to better stakeholder involvement and, as a consequence, the produced conceptual (goal) models and specifications respectively are of higher quality. In this paper, we report on our empirical investigation which show s that the use of associations between goals and video parts documenting goal achieve ments and goal failures improve the performance of typical requirements gineering tasks. More precisely, they lead to more correct and compl ete results.
