The key benefit of transitioning from Waterfall to Agile delivery is the ability to deliver value to customers earlier and more frequently.
Traditional waterfall approaches deliver value only at the end of long development cycles, increasing risk and reducing adaptability. In contrast, Agile uses iterative and incremental delivery, allowing teams to release small increments of working solutions regularly. This provides faster feedback loops, improves responsiveness to change, and enhances customer satisfaction.
From SAFe guidance:
"Agile delivery enables teams to deliver value continuously and early, ensuring that customer feedback can be incorporated to improve outcomes and minimize risk." Therefore, the correct answer is C. Ability to deliver value to customers earlier, as this encapsulates one of the main advantages of Agile over waterfall.
