What aspect of design do UX designers need to evaluate according to user-centered design methodologies?

User-centered design methodologies emphasize the importance of understanding the users' needs, preferences, and behaviors to create effective and enjoyable experiences. Evaluating user satisfaction and engagement is crucial because it allows UX designers to assess how well their designs meet the users' expectations and facilitate their interactions with the product. By prioritizing these aspects, designers can gather valuable feedback, identify areas for improvement, and enhance the overall usability of their designs.

Focusing exclusively on technical feasibility and performance metrics might overlook the user's emotional connection to the design, while considering marketing impact and brand alignment may not directly address user experience itself. Additionally, team collaboration and workflow efficiency are important elements of the design process but do not directly relate to the user's experience or satisfaction. Therefore, emphasis on user satisfaction and engagement aligns seamlessly with the core principles of user-centered design.
