User-Centered Design (UCD) is a design methodology that places the user at the forefront of the design process. This methodology involves understanding user needs, tasks, and the context in which they will use the product. UCD often includes iterative testing and refinement based on user feedback. It prioritizes user experience (UX) by ensuring that products are intuitive, accessible, and designed to meet the specific needs of end-users, ultimately leading to increased satisfaction and engagement. UCD typically incorporates techniques such as user research, personas, user journey mapping, and usability testing.
