1. Market research: Small number of people (usually between 4 and 15, but typically 8) brought together with a moderator to focus on a specific product or topic. Focus groups aim at a discussion instead of on individual responses to formal questions, and produce qualitative data (preferences and beliefs) that may or may not be representative of the general population.
2. Problem-solving: Idea generation or forecasting technique where several experts or informed individuals share their point of view on a specific topic or problem.
