Revisiting usability's three key principles

The foundations of much HCI research and practice were established over 20 years ago and elaborated as three key principles by Gould and Lewis [7]: early focus on users and tasks empirical measurement and iterative design. Close reading of this seminal paper and subsequent versions indicates that these principles evolved, and that success in establishing them within software development involved a heady mix of power and destiny. As HCI's fourth decade approaches, we reexamine the origins and status of Gould and Lewis' principles, and argue that is time to move on.
