A persona describes the typical skills, abilities, needs, desires, working habits, tasks, and backgrounds of a particular set of users. A persona is fictional reality, collecting together real data describing the important characteristics of a particular user group in a fictional character. By doing so, it becomes easier to talk and reason about the whole user group, since we can relate to, and understand individuals more easily than we can a group. Each time we refer to a persona, we feel like we are addressing an individual, but we are in effect addressing the group that the persona represents.
