A user-centric design approach is vital in product development as it prioritizes the needs and preferences of the end users. This approach ensures that the product is not only functional but also intuitive and enjoyable to use. By engaging users early through surveys, prototyping, and usability testing, developers can gather valuable feedback that leads to better user experiences and increased customer satisfaction. Moreover, a user-centric focus can enhance the product's marketability, as designs aligned with user expectations often yield greater adoption rates and overall success in the marketplace.
