Qualitative persona

A qualitative persona is built from what you learn by talking to and watching a small number of real people: interviews, contextual inquiry, diary entries. Perhaps a dozen participants, sometimes fewer. It is the classic form of the persona.

Where its strength lies

Small samples cannot tell you how many people behave a certain way. They can tell you why. A qualitative persona is strong on motive, vocabulary and context: what the person was trying to achieve, what they did instead when the product failed them, what they said to a colleague about it. Those details are what let a designer predict a reaction to a new screen.

The method is research synthesis. You group participants by shared behaviours and goals rather than by demographics, then write one persona per group, keeping real phrases from the sessions.

The limit

It cannot size a segment. If the persona says “prefers to call support”, you do not know whether that is a tenth of your users or most of them. Treat prevalence claims as unproven, and if the decision depends on them, follow up with a survey and build a statistical persona.

Common mistake

Segmenting by job title or age because it is easy to recruit that way, then discovering the personas differ in nothing that affects the design. Group by what people do, not by what they are.
