The primary role of user experience (UX) design is to enhance user satisfaction by improving the usability, accessibility, and pleasure provided in the interaction between users and products or services. UX design focuses on understanding user needs through research, design, and testing, ensuring that human-centered principles guide the development process. By creating intuitive interfaces and streamlined experiences, UX designers aim to reduce friction in user interactions, leading to higher engagement, retention, and overall satisfaction with digital products.
