An interview is designed to elicit information and requirements from a person or a group through questions and their documentation.

It implies direct communication with individuals or with groups of people who are part of an initiative.

One-on-one interviews are the most common. In a group interview (with more than one interviewee in attendance), the person in charge is careful to elicit responses from each participant.

2 types of interviews

  • Structured Interview: the interviewer asks predefined questions.

  • Unstructured Interview: the interviewer asks their questions based on interviewee responses and interactions.

Ideally, business analysts use a combination of structured and unstructured questions.
