What results from design iteration?

The process of design iteration is fundamentally about continuous improvement and refinement of a design. It often involves creating multiple prototypes or versions of a design, collecting feedback, and conducting various tests to evaluate the effectiveness of those designs. The insights gained from testing and analysis help identify what works well and what needs improvement.

Through iteration, designers can effectively learn from each version, allowing them to make informed decisions for future modifications. This cycle of feedback and analysis is crucial in enhancing the design, ensuring it meets user needs and design specifications more effectively. Thus, the outcome of this iterative process is enriched feedback, testing results, and valuable analysis that inform the next stages of design development.

The other options do not capture the essence of design iteration as precisely. Initial design sketches represent the starting phase of the design process, while cost estimation reports relate to budgeting rather than the iterative refining of design. Final presentations to stakeholders are typically the culmination of the design process rather than a result of iteration. Therefore, feedback, testing, and analysis of previous designs is the most accurate result of design iteration.
