Persona
What is a persona?
A persona is a research-based fictional character that represents a key user segment, synthesizing behavioral patterns, goals, needs, frustrations, and context into a memorable, concrete archetype.
How it works
Personas summarize recurring goals, needs and behavior from user research. Relevant attributes matter more than a fixed template or demographic detail. Teams can use them to discuss design choices, but imagining how a persona would respond is not user testing. There is no universal optimal number of personas; choose a useful set for the research and product scope.
Applied example
Imagine a health-app team whose interviews reveal three needs: tracking fitness progress, managing a condition, and completing tracking requested by a clinician. Personas could make those differences memorable, so a design for the enthusiastic exerciser does not stand in for everyone. The team would still need to test the product with real users, including people whose needs the initial research may have missed.
Why it matters
Personas make abstract user segments concrete and memorable, enabling teams to make consistent, user-centered decisions by asking what a specific person would need rather than what 'users' want in the abstract.
Evidence note: Page Laubheimer: Personas summarize evidence or assumptions; they do not replace user research.
