When should adjustments be made in an iterative design process?

Adjustments in an iterative design process should be made after testing phases based on user feedback. This approach is fundamental to iterative design, which is rooted in the idea of continuous improvement. By obtaining feedback from users during testing, designers can identify issues, gather insights on user experiences, and discover areas for enhancement. This feedback loop allows designers to refine their solutions progressively, ensuring that the final product better aligns with user needs and preferences. Adopting this method promotes a user-centered design, making it more likely that the end result will be effective and satisfactory to its intended audience.

In contrast, making adjustments only after receiving budget approval or waiting until the project is completely finished would hinder the opportunity to incorporate valuable insights gathered throughout the design process. Adjustments before any designs are created would not be relevant, as they rely on initial user feedback that can only be obtained through testing actual prototypes or designs.
