Abstract—Many requirements engineering approaches structure and specify requirements based on the notion of modes or system states. The set of all modes is usually considered as the mode model of a system or problem domain. However, it is neither clear how such a mode model can be elicited systematically, nor whether it is realistic to elicit a mode model for a productive system with regard to size and comprehensibility. In this paper, we introduce three elicitation approaches for mode models. We applied the three approaches in an industrial automotive context and assessed the resulting mode models with respect to size, complexity, and differences to each other. Our results show that all elicitation approaches were capable of eliciting modes, which were structured in mode models with 20 to 42 modes. From these results, we conclude that it is possible to elicit manageable mode models for an entire system in a productive context. In our case, the practitioners decided to integrate our ...
