What does 'iterative design' involve?

Iterative design is a critical approach in product and design development that emphasizes the importance of continuous improvement based on user feedback and testing. By focusing on prototype development and testing, designers can make informed decisions about what works well and what needs adjustment. This repetitive cycle allows for the exploration of various solutions and fosters innovation, as each iteration leads to a refined product that better meets user needs and expectations.

In contrast, the other options describe methods that lack the fundamental characteristics of iterative design. A linear design process implies a straightforward progression with a single fixed outcome, which does not allow for the fluid adjustments inherent in iterative processes. A one-time evaluation suggests a static approach where ideas are not refined or reconsidered after initial testing. Finally, a method of designing without user input ignores the essential feedback loop that underpins iterative design, resulting in products that may not address real user needs effectively.
