Contextual Inquiry Tips

  • Should be performed in teams, not by individual team members

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

Task analysis tips7 l.jpg
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
