Perfecting Your Personas
Cooper Interaction Design: A persona is a user archetype you can use to help guide decisions about product features, navigation, interactions, and even visual design. By designing for the archetype—whose goals and behavior patterns are well understood—you can satisfy the broader group of people represented by that archetype. In most cases, personas are synthesized from a series of ethnographic interviews with real people, then captured in 1-2 page descriptions that include behavior patterns, goals, skills, attitudes, and environment, with a few fictional personal details to bring the persona to life.
