This document discusses four approaches to user experience (UX) design and provides examples of projects that used each approach. The four approaches are: online surveys to collect quantitative feedback from large groups; rapid prototyping and joint application development sessions to gather early user feedback; remote and guerrilla usability testing to evaluate prototypes with real users; and eye tracking to obtain detailed insights into user behavior. Each approach is suitable for different purposes and budgets. The document advocates testing with users throughout the design process to create successful projects that satisfy users.
