User-Centered Design (UCD) is a design philosophy that prioritizes the needs, preferences, and limitations of end users throughout the development process. It involves understanding users through research and feedback, ensuring that products are tailored to enhance usability and satisfaction. UCD is commonly applied in fields like software development, product design, and web design. The UCD process typically includes stages such as user research, prototyping, and usability testing. By involving users at each stage, designers can create more effective and intuitive solutions. This approach is essential for creating products that resonate with users and meet their expectations, ultimately leading to better user experiences.
