User-centered design (UCD) is an iterative design process in which designers focus on the users and their needs in each phase of the design process. In UCD, design teams involve users throughout the design process via a variety of research and design techniques, to create highly usable and accessible products for them.

The main benefit of a user-centered design approach is that products that are created using this methodology are more likely to be successful in the marketplace. This is because they are designed with the end-user in mind, so they are more likely to be intuitive and easy to use.
