Which of the following is an advantage of Agile over Waterfall?

Agile methodology offers the significant advantage of obtaining customer feedback and refining requirements over time, which is pivotal for successful project outcomes. Unlike the Waterfall model, which follows a linear and sequential approach, Agile promotes iterative development and encourages collaboration with stakeholders throughout the project lifecycle. This allows teams to continuously gather input from users and incorporate their feedback into each iteration of the product.

As a result, requirements can evolve based on real-world testing and user interaction rather than being rigidly defined at the outset, as seen in the Waterfall approach. This adaptability helps ensure that the final product aligns more closely with customer needs and expectations, leading to higher satisfaction and better overall results.

In contrast, approaches like better documentation or sequential design may not inherently relate to the flexibility and customer-centric focus that Agile brings, nor do they encapsulate the same benefits provided by the iterative feedback loop that is central to Agile practices. Thus, the ability to refine requirements based on constant customer interaction is a hallmark advantage of Agile over traditional methodologies like Waterfall.
