Conducting an interview

Choosing participants

• cheaper for less speciales users
• if you can convince people you are imporving the world they might volunteer
• if they think is is for profict they will expect to be paid
• if you cant pay -> you cant use a token of appreciation

Process

• introduce yourself explaint he purpose
• the interview is about them, not you?
• begin with open, unbiased questions-> then follow up
• ask the questions, and let them answer
• have breaks and give them time
• have a clear separation between the general introduction, the actual interview, and post inteview discussions

Questions to avoid:

• leading questions
• what would they do / like / want in a hypothetical scenario
• how often they do things
• how much they like things on an absolute scale
• avoid binary questions

Pros/cons

• free and open answers
• sense of active contribution
• oppportunity for follow up

• time consuming and resource intensive
• dependent of commication skills of analyst
• location/schedule can make this impractical
