C Correct answer
Explanation

The primary goal of iterative design is to gather feedback from users and stakeholders to improve the product or service. This feedback is used to make changes and improvements to the product or service, which are then tested and evaluated again. This process is repeated until the product or service meets the needs of the users and stakeholders.

Multiple choice

What is the role of prototyping in iterative design?

  1. To create a high-fidelity model of the product or service.

  2. To test the product or service with users and stakeholders.

  3. To gather feedback on the product or service.

  4. To refine the design of the product or service.
