A system usage scenario illustrates how the user will interact with the system/tools in order to accomplish certain tasks. In contrast to the pedagogical and professional scenarios, the usage scenarios are focused on the interaction with the system/tools instead of accomplishing some higher-level objectives. The usage scenario shall describe typical sequences of interaction as envisioned by the stakeholders (e.g. designers, user, researchers, etc.) and gives an idea of the added value for the user. The system usage scenarios are written in plain English. These are an informal way of writing use cases. No formalism, such as UML, is used. The aim of this intermediate artefact is to facilitate the collaboration between pedagogical and technical partners when eliciting and analyzing requirements.

Together with use cases the system usage scenarios constitute the user requirements.
