A number of user-centered methods for designing radiology workstations have been described by researchers at Carleton University (Ottawa), Georgetown University, George Washington University, and University of Arizona, among others. The approach described here differs in that it enriches standard human-factors practices with methods adapted from ethnography to study users (in this case, diagnostic radiologists) as members of a distinct culture. The overall approach combines several methods; the core method, based on ethnographic ''stream of behavior chronicles'' and their analysis, has four phases: (1) first, we gather the stream of behavior by videotaping a radiologist as he or she works; (2) we view the tape ourselves and formulate questions and hypothesis about the work; and then (3) in a second videotaped session, we show the radiologist the original tape and ask for a running commentary on the work, into which, at the appropriate points, we interject our questions for clarification. We then (4) categorize/index the behavior on the ''raw data'' tapes for various kinds of follow-on analysis. We describe and illustrate this method in detail, describe how we analyze the ''raw data'' videotapes and the commentary tapes, and explain how the method can be integrated into an overall user-centered design process based on standard human-factors techniques.
