What does "design iteration" involve?

Design iteration is a fundamental principle in the engineering and design process that emphasizes the importance of continuous improvement. It involves repeatedly refining and enhancing a design based on feedback and testing. This method allows designers to identify potential issues, gather user input, and make necessary adjustments to improve functionality, aesthetics, or usability.

In practice, design iteration encourages an iterative loop where each version of the design is tested and evaluated. Feedback from testing is crucial as it informs the next cycle of design adjustments, ensuring that the final product meets user needs and expectations more effectively. This approach fosters innovation and helps to mitigate risks associated with launching a final product that may not adequately address the design challenges.

The concept relies on the understanding that initial ideas often need to be revised and that the first iteration is rarely the final one. This method contrasts with approaches that prioritize reaching a conclusive design quickly without incorporating data from testing or user feedback. By valuing the ongoing process of refinement, design iteration ultimately leads to higher quality outcomes.
