Focus groups are small, structured discussion groups that are used to gather feedback and opinions on a particular product, service, or topic. They are typically composed of 6-12 participants who are representative of a target audience or customer segment. Focus groups are facilitated by a moderator who asks open-ended questions and encourages discussion among participants. Effective management of focus groups involves identifying the appropriate target audience, recruiting participants, designing effective questions, moderating the discussion, and analyzing the results. Focus groups can provide valuable insights into customer needs, preferences, and opinions, and can be used to inform product development, marketing strategies, and business decisions.
