This paper argues the flexibility of focus group in Design research as a controlled-experiment setting to study Designerly Intuition at concept-stage decision making. This paper outlines the focus group design in terms of the types and structure considerations and the moderator factor. Finally, the focus-group result gathers dual-mode input from novice Industrial Designers (1) 'as a group' and the intuitive attributes as (2) ‘individual participants’. Therefore, the focus group design for the data collection setting is established through the research layout and space design that accommodates both modes of inquiry.
