What defines the success of an iterative design approach?

The success of an iterative design approach is primarily defined by positive user engagement and satisfaction. This approach emphasizes continuous feedback and improvement based on user interactions with the design. By focusing on the users' experiences, designers can make informed decisions about what adjustments need to be made to better meet user needs and preferences.

User satisfaction is a crucial metric because it reflects how well the design fulfills its intended purpose and how effectively it resonates with the target audience. High engagement and satisfaction indicate that the iterative process is effectively tuning the design to match user expectations, thereby increasing the likelihood of a successful final product. This user-centric focus differentiates iterative design from traditional design methods that may prioritize completion timelines or technical complexity over user experiences.
