A discussion guide is the foundational planning document for qualitative research, used in moderator-led interviews, focus groups, and AI-moderated sessions to structure the conversation without over-scripting it. A well-designed discussion guide balances research objectives with conversational flow, grouping questions into logical sections that move from broad context-setting to specific probes. In research operations, the quality of a discussion guide directly affects the depth and usability of findings. Poorly constructed guides produce shallow responses; well-constructed ones surface the motivations, tensions, and language that stakeholders need to make confident decisions. Discussion guide design is a core skill in qualitative methodology, requiring clear thinking about what the business actually needs to learn.
