Iterative design is a process used in various fields, including software development and product design, where a product is developed through repeated cycles of prototyping, testing, and refining. This approach allows designers to gather feedback and make improvements at each stage, ensuring that the final product better meets user needs and expectations. In iterative design, each version of the product, known as a prototype, is evaluated for usability and functionality. Based on the feedback received, designers make necessary adjustments before creating the next version. This cycle continues until the product achieves the desired quality and effectiveness.
