What aspect of the Sprint Backlog allows it to be adaptable?

The adaptability of the Sprint Backlog primarily stems from the ability to change tasks based on feedback. This characteristic is crucial in Scrum because it aligns with the framework's emphasis on iterative development and responding to changes in requirements. During the Sprint, the team may receive feedback from stakeholders or discover new insights while working on the product. This ongoing feedback loop allows the team to adjust the tasks within the Sprint Backlog, ensuring that it remains relevant and aligned with the project goals.

In Scrum, the Sprint Backlog is intentionally designed to be a living artifact. It evolves throughout the Sprint, reflecting both the team's progress and any new information that may necessitate adjustments. This flexibility enables the team to prioritize the most valuable work and facilitate better outcomes for the product being developed.

In contrast, the other options do not support adaptability. Detailed specifications can lead to a rigid approach, fixed sets of tasks limit flexibility, and reliance on historical data may not account for current realities. Hence, the ability to adjust tasks based on real-time feedback is what empowers teams to remain nimble and responsive to change within their development process.
