Answer:
Iterative design does present difficulties as a creative process. It requires the designer to be tenacious and willing to accept multiple failures before the correct solution is found. It also requires significant amounts of materials, as multiple versions of the same product will need to be created.
Step-by-step explanation:
Iterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Based on the results of testing the most recent iteration of a design, changes and refinements are made. This process is intended to ultimately improve the quality and functionality of a design. In iterative design, interaction with the designed system is used as a form of research for informing and evolving a project, as successive versions, or iterations of a design are implemented.
