Design evaluation is a research area that focuses on assessing and critiquing the effectiveness, usability, and overall quality of a design. This evaluation process typically involves collecting feedback from users, experts, or stakeholders to identify areas for improvement and ensure that the design meets its intended goals and objectives. Design evaluation often involves the use of various methods such as surveys, interviews, usability testing, and heuristic evaluations to gather data and insights about the design. The findings from a design evaluation can help designers make informed decisions about how to iterate and refine their designs to better meet the needs and expectations of the end-users.
