Problems and Benefits of Requirements Gathering With Focus Groups: A Case Study

Abstract

Focus group interviews are considered as a rather weak, nonquantitative method of assessing user needs, ideas, and reactions in an early stage of the interface design process (Nielsen, 1993). Given this fact, it is relevant to reflect the practical use of focus groups step by step to determine their real strengths and limitations. In this article, we share our experience of planning, running, and analyzing focus groups within the design process of a home automation system. We describe the pre- and postwork in detail so that the pros and cons of gathering requirements with focus groups become apparent.
