**What is the significance of user experience research in product design?**
**User experience (UX) research** is significant in product design because it informs the development process by understanding users' needs, behaviors, and preferences. Through methods like interviews, surveys, usability testing, and observations, UX research helps identify pain points and areas for improvement in products. By integrating user feedback, designers can create solutions that are more intuitive, efficient, and satisfactory to the end-users. This leads to better user engagement, higher customer satisfaction, and greater product success in the market. Ultimately, UX research is essential for creating user-centered designs.
