Focus Groups are an informal assembly of users whose opinions are requested about a specific topic. The goal is to elicit perceptions, feelings, attitudes and ideas of participants about the topic.
Pros and cons of Focus Groups
Pros:
Way of gathering detailed information and views about a product or service
Useful for obtaining range of opinions rather than strength of opinions
Cons:
May not have a very high uptake as customers need to devote time
May have problems recruiting for group - use incentives
Results should not be generalized or 'projected' to a larger group
Risk participants might influence each other or inhibit others from sharing honest thoughts or feedback
