FFocus groups are usually composed of 10 to 15 people as participants. They are small groups who are asked to answer a series of questions about a particular product or a service. Focus group participants can be specialists in the field of the product or service that is being surveyed or they can be drawn from a cross-section of the general population. The results from the survey are used to help companies focus on what the areas they need to concentrate on to make the product a success.
