Persona

What is a persona?

A persona is a made-up person who represents a real group of users. It brings together the goals, tasks, context and typical obstacles of that group in one tangible profile, usually with a name and a short description. It turns "our target audience" into a specific person a team can talk about.

The method was made popular by software developer Alan Cooper, particularly through his 1999 book "The Inmates Are Running the Asylum". The key point: a persona is only as good as the research behind it.

Why personas matter

Without a shared picture of users, everyone on the team designs for someone different, often for themselves. Personas create a common language and help justify decisions: Does this feature help our primary persona, or is it just a request from sales? They also make it clear that different groups have different needs, such as first-time buyers and loyal customers in an online store.

How to use personas in practice

• Build on data: Base personas on interviews, user tests and usage data, not gut feeling.
• Focus on behavior: Goals, tasks and obstacles matter more than age or hobbies.
• Keep it small: Two to four personas are usually enough, with one as the primary.
• Use them day to day: Refer to specific personas in reviews and when setting priorities.
• Revisit them: Update personas as new insights come in.

Common mistakes

Personas are often created in a single workshop, filled with stock photos and demographic details, and then forgotten in a folder. Profiles like that look convincing but rest on assumptions, and they can even steer a team in the wrong direction.
