How can the effectiveness of a design solution be evaluated?

The effectiveness of a design solution can be evaluated by testing it against specific criteria and obtaining feedback from users. This approach allows designers to assess how well the solution meets the intended purpose, functionality, and user requirements. Gathering user feedback is crucial because it provides real-world insights into how the design performs in practice. This information can highlight strengths and areas for improvement, ensuring that the final product aligns with user needs and expectations.

In contrast, while comparing to past designs may provide some context, it does not focus on the current solution's specific performance or user experience. Checking market value involves understanding financial aspects but does not directly measure the design's functionality or effectiveness. Considering the designer's intent offers insight into the creative process but does not provide a comprehensive evaluation of the design's performance in real-world applications. Therefore, testing and feedback directly inform improvements and refinements in the design solution.
