Personas 14 Feb 2006

Personas Developed by Alan Cooper A user archetype used to help guide decisions about product features, navigation, and visual design

Who are the important users? Always more than one group of users (if only beginner, intermediate, advanced) What technologies do they use? Essential to understand information needs of audience (and their vocabulary!) How else can you organize content so that they can find what they are looking for?

Know your site visitors ID audience segments, prioritize Use log files Consider privacy issues Personalization Cookies Create personas based on research (ideal) or ad hoc (Norman)

Ideal Persona Development Synthesized from a interviews with real people Summarized description includes behavior patterns, goals, skills, attitudes

Persona Descriptions Personas represent behavior patterns, not job descriptions! It’s not a list of tasks, although the narrative that describes the flow will touch on tasks

Experience Goals How the persona wants to feel when using a product Having fun and not feeling stupid are experience goals Usually there is one persona to represent those of us with a lot of anxiety about technology From Perfecting Your Personas

End Goals What happens when the persona uses the product? Create an award-winning publication Become more efficient with time Reduce accounting errors

For someone active like Greg, the site's design needed to be accessible and quick to use.
