Abstract:

A focus group is a focused discussion where a moderator leads a group of participants through a set of questions on a particular topic. Focus groups are often used in the early stages of product planning and requirements gathering to obtain feedback about users, products, concepts, prototypes, tasks, strategies, and environments. Focus groups can also be used to obtain consensus about specific issues.
