The purpose of Personas is to put a face and
a name to the vague and mysterious "users." With a persona
representing each category of users, designers can communicate clearly
with each other about interface goals, user preferences and priorities.
In this, our first real use of Personas, we created
a detailed personality for each of 6 people (developed from interviews
with customers, support personnel, etc). Details about their pet
peeves on the job, a day in their life, and insights into their
personal lives made each Persona more believable.
