What does the term "iteration" refer to in the context of design?

In the context of design, "iteration" refers specifically to the process of making repeated refinements to a design based on testing results. This approach is fundamental in engineering and design fields, as it allows designers to continually assess the performance and functionality of their prototypes or concepts. Through iterative cycles, designers gather feedback, identify problems, and make necessary adjustments, leading to improved versions of the design over time.

Iteration is essential because it emphasizes the importance of testing and validation in the design process. Instead of settling on an initial idea, designers engage in a cycle of testing, evaluation, and modification, which fosters innovation and enables the development of more effective solutions. By embracing iteration, engineers and designers can ensure that their final product is well-tested, reliable, and meets user needs effectively.
