Iterative design is a process used in product development where a design is continuously improved through repeated cycles. Each cycle involves creating a prototype, testing it, gathering feedback, and making necessary adjustments. This approach allows designers to refine their ideas based on real user experiences and preferences. The goal of iterative design is to enhance usability and functionality over time. By incorporating user feedback at each stage, designers can identify issues early and make informed decisions, ultimately leading to a more effective and user-friendly final product. This method is commonly used in fields like software development and product design.
