The work reported here integrates an analytical evaluation technique, Programmable User Modelling, with established knowledge elicitation techniques; the choice of techniques is guided by a selection framework, ACRE. The study was conducted in conjunction with an ongoing industrial design project. Techniques were selected to obtain domain knowledge in a systematic way; the rationale behind each choice is discussed. The use of "negative scenarios" as a means of assessing the severity of usability findings is introduced.
