What does "iteration" refer to in the design process?

In the design process, "iteration" refers to the repetition of a process within a design cycle aimed at refining and improving outcomes based on feedback and testing. This concept is crucial because it emphasizes that design is not a one-time event but rather an evolving and dynamic process. Each iteration allows designers to incorporate lessons learned from previous attempts, leading to enhanced functionality, usability, and overall quality of the product.

Designers often create prototypes or preliminary versions of a product, evaluate them, and gather feedback. They then use that feedback to make informed adjustments. This cycle continues until the design meets the desired specifications and user needs effectively, resulting in a more refined final product.

This approach contrasts with the final review stage, initial brainstorming, or marketing strategies, which do not inherently involve the process of continuous improvement through repetition and feedback. Instead, iteration focuses on the active process of developing and enhancing a design through repeated cycles of testing and refinement.
