First Impressions
● Impressions are formed by 50ms
● Primarily based on visual appeal
● Do not change with additional viewing time
● Are not influenced by actual usability issues

Rapid Iterative Testing & Evaluation
(RITE)
Identify critical problems and fix them on the fly
● Representative users, actual tasks, interactive interface
● Involve key decision makers (PM, design, development)
● Agree on critical problems and make changes to interface after each session
