Representations are considered to be means for better communication and collaboration in determining software requirements. Uses of representations have normally been studied in artificially created situations characterized by a harmonic common interest. Representations then can be seen as props for hearing the users' voice in requirements analysis. Two episodes in a 'real world' requirements determination session are analyzed not only in a responsive but also in a rhetoric light. A high-fidelity prototype as a representation in concert with a free flow of control could be seen to hinder the democratic determination of the requirements, and to enable rhetorical persuasion.
