User persona
Definition
A user persona is a research-based representation of a key type of user — capturing their goals, frustrations, context, and behaviors — intended to help the product team make decisions as if the user were in the room.
Alan Cooper introduced personas in The Inmates Are Running the Asylum (1999). The idea: instead of designing for an abstract "average user," teams build for named, specific archetypes grounded in real user research.
A useful persona answers three questions: Who is this person in context? What are they trying to accomplish? What frustrates or blocks them today?
Most personas are built wrong. The common mistake is filling in demographic fields (age, city, job title, marital status) instead of behavioral fields. Whether a user is 32 or 45 matters less than whether they're a first-time buyer or a repeat purchaser, whether they're deadline-driven or exploratory, whether they share outputs with a team or use them solo.
The second common mistake is building personas from assumption rather than research. A persona that isn't grounded in actual user interviews is a team's existing beliefs, formatted as a character. It feels like research but produces the same conclusions as no research.
Personas should be differentiated enough to produce different design decisions. If two personas would make the same choice in every scenario, they're not meaningfully different.
Personas are often drawn on whiteboards — the team sketches the archetype, writes the key frustrations, and maps the typical workflow. BoardSnap captures those sessions as structured summaries that stay searchable long after the whiteboard gets erased.
Examples
- A PM persona: "Alex, the solo founder who runs weekly strategy sessions and needs to ship notes fast"
- A student persona: "Maya, the pre-med student photographing lecture diagrams to study later"
- A persona built from synthesis of twelve user interviews, not from team assumptions
- Two personas on a whiteboard with side-by-side frustrations and goal comparisons

BoardSnap turns any whiteboard — including this one — into a summary and action plan.
