Focus Groups
This is a group of subjects who are chosen to test and self-report their experiences of using a product, system, or service. Focus group sessions are generally facilitated by a skilled moderator to gain valuable information about the needs, expectations, and problems of users (Eysenbach & Kohler, 2002).
