Answer:
D. Iterative design
Step-by-step explanation:
An iterative design can be defined as a cyclic process which typically involves prototyping, testing, evaluating or analyzing and refining of a product, so as to continually improve the product.
In an iterative design process, the following steps are adopted;
1. A prototype of the product is first created and tested by the manufacturer.
2. The product is then evaluated to check for any defect or flaw.
3. The defect or flaw is fixed through a refining process.
4. The previous steps are repeated incrementally until an improved version of the product is created.
Hence, cycling through the design process to create several models that incrementally improve a solution is called iterative design.
