Personas: Setting the Stage for Building Usable Information Sites
As long as personas are developed with diligence, the planning and development tool has three key benefits for interface design projects of all kinds. First, personas introduce teams to hypothetical users who have names, personal traits, and habits that in a relatively short time become believable constructs for honing design specifications. Second, personas are stand-ins with archetypal characteristics that represent a much larger group of users. Third, personas give design teams a strong sense of what users' goals are and what an interface needs to fulfill them.
