Focus group
A focus group (also known as a "focus group interview") is a group interview that focuses upon a particular issue, product, service or topic by encouraging discussion among participants and the sharing of perceptions in an open and tolerant environment. Participant interaction is a key feature of focus group design, which is used (1) to reveal the preheld views of participants about a particular issue or topic (positivist or critical realist perspective), and (2) analyse how participant interactions and group dynamics lead to the construction of shared meanings (interpretivist perspective). Participants are normally chosen with a specific purpose in mind, such as they are typical of the group being researched or they represent those who are critical to a particular operation, in other words participants are "information rich" (Saunders et al., 2016).
