Which characteristic defines Agile methodology in software development?

Agile methodology is defined by its focus on iterative development and incremental delivery. This approach allows teams to develop software in small, manageable segments, called iterations or sprints. Each iteration produces a potentially shippable product increment, enabling teams to release features swiftly and gather user feedback frequently. This adaptability ensures that evolving requirements can be addressed continuously, reflecting changes in stakeholder needs and market conditions.

The iterative nature of Agile also encourages regular reflection and adjustment of processes, which enhances both team performance and product quality. By breaking the development process into smaller increments, Agile practices promote a more flexible environment where changes can be seamlessly integrated, as opposed to the rigidity found in more traditional methodologies. This characteristic is integral to Agile's effectiveness, making it highly suitable for projects where requirements are expected to change.

In contrast, other methodologies may emphasize fixed requirements, sequential development, or prolonged delivery cycles, which do not align with the Agile philosophy of responding to change and promoting collaboration through continuous feedback.
