Why is testing an integral part of the iterative design process?

Testing is an integral part of the iterative design process because it provides valuable data that can guide modifications to the design. By conducting tests, designers can gather insights into how users interact with the product, what features are effective, and where improvements are necessary. This data-driven approach allows designers to make informed decisions and refine their designs based on actual user experience rather than assumptions.

The iterative design process thrives on feedback and continuous improvement. Testing helps identify strengths and weaknesses in the design, ensuring that the end product aligns better with user needs and expectations. Ultimately, this leads to a more effective and user-friendly design, demonstrating the critical role of testing in enhancing overall design quality.
