Numbers tell you what people do. Qualitative research tells you why. The two most common qualitative methods are focus group discussions (FGDs) and in-depth interviews (IDIs). Choosing the right one saves time and money.
Focus group discussions
A trained moderator leads a discussion with a small group of similar people, usually six to eight. Group energy sparks ideas and reveals shared opinions.
Best for: exploring new product ideas, testing advertising, understanding everyday habits and language.
In-depth interviews
A researcher talks one-to-one with a respondent for 30 to 60 minutes, going deeper into personal experiences and decisions.
Best for: sensitive topics such as health or finance, senior business decision-makers, doctors and experts, and complex purchase journeys.

The Indian context
Language, gender and seniority shape how openly people speak. Groups should be conducted in the respondents’ own language, with similar participants in each group, and moderators who understand local culture.
