Usability Testing
Usability testing is a UX research method where real users attempt to complete specific tasks while observers note difficulties, confusion, and behavior patterns. It can be moderated (with a facilitator) or unmoderated (self-guided with recording), and conducted on prototypes or live products. Even testing with just 5 users typically uncovers the majority of usability issues, making it one of the highest-ROI activities in product development.
