What part of the design process is characterized by iteration?

The design phase is characterized by iteration because it involves generating and refining design ideas based on user feedback and testing findings. During this phase, designers create wireframes, prototypes, and mockups and continuously revisit and revise these designs to improve functionality and user experience. This iterative approach allows for flexibility, enabling designers to explore various solutions, address potential issues early in the process, and align the product more closely with user needs and preferences.

Iteration is crucial in the design phase to foster creativity and collaboration, as designers often go through multiple cycles of designing, receiving feedback, and making adjustments before arriving at a final design. This process ensures that the end product is well thought out and effectively meets user expectations.

In contrast, the other phases are more focused on specific tasks that do not emphasize the iterative nature to the same extent. For instance, the development phase typically involves implementation of the finalized designs, the testing phase focuses on evaluating the already developed product, and the implementation phase is about deploying the product, which generally does not involve reworking designs based on iteration.
