Final answer:
Feedback is essential for continuous improvement and iteration, which are key to the incremental and spiral design processes used in developing and enhancing digital products.
Step-by-step explanation:
Feedback is critical to continuous improvement, a formal set of processes many companies use to evaluate and improve their products and operations, on an ongoing basis. In digital products, improvements are often achieved through incremental design, where the development cycle is performed multiple times, adding new features or enhancing the product each time.
The design process is iterative and may require multiple cycles of prototyping, testing, and refinement. This agile approach allows for the spiral design process, where testing and evaluation of prototypes inform ongoing improvements and adaptations to the design.
The term that best completes the first sentence is continuous improvement. Continuous improvement is a formal set of processes that companies use to evaluate and improve their products and operations on an ongoing basis.
The term that best completes the second sentence is product development. In digital products, improvements are often achieved through product development, where the development cycle is performed multiple times, adding new features or enhancing the product each time.
