contextual inquiry tips
Contextual Inquiry Tips
  • Should be performed in teams, not by individual team members
    • Interviewers: Different perspectives help create better understanding of users
    • Note-taker: Record interesting events to look at later
    • Photo, tape recorder, video
  • Try out different roles in each interview
contextual inquiry tips4
Contextual Inquiry Tips
  • Use time after interview to analyze info and refocus for next interview
  • Refocusing includes choosing subsequent interviewees
  • Select interviewees who can develop our understanding of the users, their tasks and work contexts

contextual inquiry tips5
Contextual Inquiry Tips
  • Make preliminary notes to focus interviews
  • Clarify notes with interviewees
  • If they use computers, ask what workarounds they resort to
  • Don’t talk all the time
  • Resume with interviewee’s words or thoughts if interrupt at an inconvenient time

Karen Holtzblatt and Sandra Jones. “Conducting and Analyzing a Contextual Interview,” in Schuler and Namioka, Participatory Design: Principles and Practices, Lawrence Erlbaum Associates, 1993.

task analysis tips
Task Analysis Tips
  • Use the questions from lecture
  • Easiest to work from transcripts
  • Team analysis of interview transcripts
    • Saves time in the long run
    • Builds team ownership
    • Come out with a clear understanding of the group’s focus

task analysis tips7
Task Analysis Tips
  • Analyzing results is not the same as picking a final design
    • Don’t skip “ludicrous” ideas immediately
    • Don’t structure/categorize too early
    • Consider affinity diagrams
    • (http://www.balancedscorecard.org/files/affinity.pdf)
  • Use and reuse the interviewees’ language
  • May need to validate interpretation with original interviewee
