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, continuedDo this separately for each location

And then combine
