Focus group

As explained in Design for Developers

A focus group is a moderated discussion in which multiple users or participants provide qualitative information about a topic, product, or experience.

A focus group is a qualitative research discussion with 5 to 10 participants. It gathers opinions, attitudes, and beliefs about a product, feature, or topic, while letting the moderator ask follow-up questions and steer the conversation toward useful detail. section 4.2.3

Use a focus group early to learn how people perceive a product, or later to explore reactions to a design. Questions can address a proposed product, competitors, or a general product area before a design exists. The goal is insight into what users like, dislike, expect, and find problematic—not copying competitors. section 4.2.3

Plan the session around discussion rather than simple responses:

  • Recruit people who understand the topic or product area. section 4.2.3
  • Include both users of similar products and prospective users. section 4.2.3
  • Prepare specific follow-up questions that uncover reasons behind answers. section 4.2.3

Exploring an unfinished website idea

Before designing a new site, bring together people familiar with the product area and prospective users. Ask what they like or dislike about comparable experiences, then probe unclear answers to identify expectations and problems worth addressing. section 4.2.3

How Design for Developers covers it

How deep it goes
Defines group size and qualitative purpose, then gives recruitment, timing, and moderation guidance without detailing analysis methods.
Examples
Illustrates pre-design questioning through competitors or a generalized product without competitor names.
What it assumes
Assumes participants know the topic or product area and teaches selection of similar-product users and prospective users.
What you can do after
Apply it to recruit an informed mixed group and probe discussion for actionable product insight.
How it connects
Connects qualitative research with surveys, competitive analysis, user perceptions, and prospective users.
