Which concept emphasizes the use of user feedback in product design?

The concept that emphasizes the use of user feedback in product design is user-based design. This approach prioritizes understanding the needs, preferences, and experiences of users throughout the design process. By actively involving users and soliciting their feedback, designers can create products that better meet user expectations, enhance usability, and ultimately ensure a more satisfying user experience.

In user-based design, techniques such as usability testing, surveys, and interviews are commonly used to gather insights directly from the target audience. This continuous loop of feedback allows designers to iterate and improve their products based on real-world input, making the final outcome more aligned with what users genuinely want and need.

In contrast, other concepts may not focus primarily on user feedback. Development may refer to the technical aspects and stages of building a product, while data could pertain to the quantitative metrics collected during the design process but does not inherently emphasize user involvement. Experience goals often relate to the desired outcomes or emotional responses aimed for in a design but do not specifically highlight the role of user feedback in shaping those outcomes.
