Usability

Individual Interviews typically refers to talking with one user at a time face to face, by telephone, or with instant messaging or other computer-aided means. It is important to write an interview protocol that includes questions and probes to use for follow-up. Individual Interviews resemble Focus Groups because they involve talking with users. The main difference between Individual Interviews and Focus Groups is that researchers are talking to one person at a time. In an Individual Interview:

• You have more time to discuss topics in detail.
• You do not have to worry about the group dynamics that inevitably occurs in Focus Groups. 
• You can give the interviewee your full attention and adjust interviewing techniques.

The purpose of Individual Interviews is to give you a deep understanding of the people who visit a website. Individual Interviews are typically used to supplement Online Surveys.
