General Comments
• At Light House, session was, like ANC, more of an
interview than a contextual inquiry
• Further interviews/observations likely needed
• Iteration!
• Don’t be surprised or discouraged if you missed important
points

HPC interviews vs. contextual design
• HTC:
• many people, one interviewee
• No recording
• Contextual inquiry
• one/two interviewer(s), one interviewee
• record/transcribe
• We will have less detail/less fidelity than we might like

Game Plan
• Each person’s notes are tracked as one “interview”
• Write down data about user
• Go over notes
• Recorder: writes down key observation, insight, influence,
question, design idea, breakdown
• Not steps in sequences/communication - those go in..
• Work modelers: draw flow, cultural, and process map
models as we go
• Rat hole watcher: make sure we don’t get distracted

Game Plan, continued
Do this separately for each location
And then combine
Additional notes for other details
information recorded at registration?
