Pre-Interview Checklist

1. Decide what goals you want to accomplish
2. Prepare a list of questions
   • Ask about things you know you need to find out, based on your current understanding of the requirements
   • Keep questions simple. Don't use multi-part questions, break complex topics into individual questions.
   • Confirm key assumptions. E.g., "You are the one who actually would use this software, right?" "The total needs to be displayed and updated as each item is scanned, right?"
   • Avoid leading or multiple-choice questions because the right answer might be one that you don't know about yet. E.g., WRONG: "Would you log in to the system from your desk here or from home?" RIGHT: "Where are some of the places you would be sitting when you log in?" "Here in my office, but also when I work with others sometimes I log in from their office or from a machine in the lab or conference room... so, I don't want a cookie saved there."
   • Try to find out the priority of each requirement: essential, expected, desired, or optional.
   • Write some more open-ended questions to see if new important requirements come up.
   • Don't ask too many questions that seem out of scope, you could accidentally change the scope or set incorrect expectations. E.g., "Would you like the system to also do ten other cool things?" "Sure!"
3. Select interviewees that represent all important stakeholders
4. Review your questions. Do you think they can be answered? Will they help achieve your goals? If not, go back and revise.
5. Decide whether you want to do this interview via email, telephone, or in person
6. Schedule an interview a time and place for the interviewee's convenience. Plan on the interview lasting one hour.

Interview Checklist

1. Be prompt, courteous, and business-like
2. Introduce yourself and explain why you are there
3. Make sure that you are interviewing the person you think you are. Get their contact information (e.g., email address) if you don't already have it.
4. Ask permission to take notes. Don't record or video tape.
5. Confirm the amount of time you and the interviewee have for this session.
6. Give a quick indication of the type and number of questions that you have
7. Work through the questions.
8. Listen. That is why you are there.
9. If the interviewee refers to existing documents, systems, equipment, or people, make sure that you understand what he or she is talking about. If it is important, ask if you may have a copy or screenshot (but, don't ask for anything containing proprietary information), or make a note of the important aspects of the items referred to. Note the URLs of any existing public websites discussed.
10. Try not to answer the questions yourself, or to react to interviewee requests by making promises to solve problems. Interviews are for understanding the problems, not solving them or setting schedules or deliverables.
11. Write down action items to follow up on finding more information. E.g., if the interviewee starts explaining at length something that you know you can learn on your own, or if they don't know the answer and start speculating at length, you should try to move on the next question.
12. If you find that you have prepared the wrong questions, focus on getting information that will help you prepare the right follow-up questions.
13. Finish on time. If you need more time, continue via email or another meeting.
14. Summarize action items that you will follow up on
15. Ask if the interviewee has any questions for you, or if there was something more that they wanted you to ask.
16. Make sure to leave contact information
17. Thank the interviewee for their time

   • Thank the interviewee again
   • Confirm that you have their correct email address, and make it easier for them to reply to you
   • Ask any important follow-up questions
   • Give status on your action items, if any. E.g., "I searched Google for that product you mentioned and I couldn't find a users manual, but I did find a magazine review of it." Or, "After I interviewed you, I spoke with Bob, and he confirmed that some current products do cost $0.00."
