Throughout the history of HCI, interviews have been utilized for collecting users' subjective evaluations of interactive technology. This paper raises the issue that these interviews are often deployed in a manner overlooking two aspects of evaluation: the relative positions from which the system is evaluated and the interviewees' interpretations of the system. In the study, 14 users of a new information system were asked to evaluate provocative claims about the system's usability. The analyses of their responses reveal two sources of variation: what is being evaluated and who is evaluating it. Interviewees evaluated the system's usability from five user positions: end user, supervisor, organization's representative, co-developer, and outsider. Also, four "faces" of the system were interpreted: UI, utility, communication medium, and unknown entity. These findings are employed for drawing of broader conclusions about the system and its use, and procedures for improving user interviews in HCI are presented.
