When do have to move on? Give clues about the level of detail you want 28

Recording the Interview Best memory mechanism Full transcription or just verbatim quotes Still take notes Tapes fail, digital files are deleted Does not record all aspects (esp. context / facial expressions) Required consent Always ask first. Do NOT hide recorder, keep it visible at all times. Give the option to turn it off at any point. 31

Recording the Interview Partner-based interviewing Advantages of a single contact vs. trading-off Can share roles (interviewer/scribe) BOTH take notes, though to different degree Group debrief: what did you get/miss? Sync notes: overlap and emphasis Clarify while it is still in your head 33

Writing up the Interview 35 How detailed? Verbatim transcript only possible with audiorecording Extremely labor-intensive Summaries with major points quoted OK, but use LOTS of quotes Start closer to verbatim at the beginning of a study Plan to spend twice as much time writing up as you did in the original interview

Interviews (DWR) Strengths Interviewee can respond freely and openly to questions. Interviewee can be asked for more feedback. Questions can be adapted or reworded for each individual. Interviewee’s nonverbal communication can be observed. Weaknesses Very time-consuming, and therefore costly, fact-finding approach. Success is highly dependent on the systems analyst's human relations skills. May be impractical due to the location of interviewees.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
