Collect the demographics of each interviewee and include it in your report. (age, occupation, sex, interests that apply, geographic location, etc.)
In some cases you will need a release form (external link) signed by each interviewee. This insures that the interviewee understands that there will be no compensation for their words or appearances in photography or video, and, that these will be made available for public viewing.
Ask the interviewee if you will need to submit to a background check or sign a non-disclosure agreement. Get that done before you arrive.
If you need specific technology: list that and send it to your interviewee. Going on sit e ahead of time is good practice if it is possible.
If you may be working as a team, meet prior to the interview to set roles.... such as Interviewer, Note Taker, Photographer, Set Dresser (adjusts backgrounds for photographer), Food and Snacks.
Follow Up Questions are sometimes required to insure all of the information you desire is captured. Write down all of the potential follow up questions your team can generate. Try to build on one another’s ideas in order to flesh out meaningful subject areas.
Identify themes or subject areas into which most questions fall; once you’ve identified the themes of your question-pool, determine the order that would allow the conversation to flow most naturally.
Make sure that you leave room in your planning to ask plenty of “why?” questions, plenty of “tell me about the last time you _____?” questions, and plenty of questions that are directed at how the user Feels.
