Efficient usage of applications often requires context-aware applications. We assume that context-aware adaption can be useful in the case of crisis management tools as well, where fast responses are crucial and can be supported by information technology. A small user study performed with a crisis response team mostly composed of fireman supports our assumptions for the important case of role-aware messaging applications. We demonstrate our way to develop context-aware user interfaces using our model-to-model transformation language with constraint solving and apply it to the case of a crisis management system.
