System prototyping is becoming very popular, as it enables to understand customer ___ at an early stage of development.*0 pointsOpinionDevelopmentRequirements

The correct answer to fill in the blank is "Requirements."

Explanation:

System prototyping is a crucial phase in the software development lifecycle because it helps bridge the gap between customer expectations and the final product. By creating a prototype—whether it's a low-fidelity mockup or a high-fidelity interactive version—developers and stakeholders can visualize specific functionalities early in the development process.

This iterative method encourages feedback and collaborative discussions, allowing developers to adjust the system based on user feedback. Consequently, understanding customer requirements at this early stage can significantly reduce the risk of project failure. It ensures that the end product aligns closely with what the customer actually needs and desires, rather than what the developers assume they want.

Therefore, in the given context, "Requirements" is the term that best completes the sentence.
