The objective of creating user personas in design is to represent the various segments of target users, guiding the development of user-centered products and services. These personas are fictional characters based on real data that summarize users' goals, behaviors, and challenges. By utilizing user personas, designers can empathize with different user needs and tailor interfaces and functionalities accordingly. This process enhances usability and satisfaction, ensuring that the final product resonates with its intended audience while effectively addressing their specific requirements.
