2005 UPA Member and Salary Survey
Are you curious about your colleagues' salaries? Job titles? Do you wonder what methods your colleagues use? The Usability Professionals' Association periodically surveys the membership and others in the user experience field to learn more about who we are, where we work and what we do.

Thumbnail: Carolyn Snyder
Carolyn Snyder is into paper. Her book Paper Prototyping: The Fast and Easy Way to Design and Refine User Interfaces is considered the first and last word on the subject.
