Opinions can be valuable, but consensus is typically much more valuable. Crucial for many a qualitative study, focus group interviews enable businesses to average customer input while also receiving detailed feedback. The method is particularly good for investigating central targets, and there is lots of navigability when selecting participants. Tapping into best available insight, however, depends on numerous factors.
- Multiple participants– While there is no set size, focus groups typically comprise anywhere from six to 10 participants. The idea is to maximize variety while also fostering critical input. No more than six participants is best for maximizing engagement.
- Moderator direction- Encouraging participant feedback is crucial, and focus groups require a moderator to run the show. These researchers maximize clear communication, impartiality, and productive discourse.
- Sufficient time- There will always be extremes and exceptions, but most focus group discussions require between 60 and 90 minutes. Going under 60 minutes leads to less insight, while going over can strain participants and effect their answers.
- Effective structure- Near all formal interviews structure around set questions, and focus groups are no different. Within said structure, however, there also needs to be free-form dialogue. All focus groups should include a good amount of spontaneity.
- Limited contact- Small group dynamics can get complicated quickly. One real hazard, however, is allowing participants to become too familiar with each other. The best answers come from a participant’s own opinion, not one influenced by the rest of the group.
- Multiple sessions with new participants- Focus groups can be stand alone, but this often overemphasizes one group’s input. Multiple sessions with carefully selected, one-off participants is standard.
