What model of software development features iterative cycles rather than a linear process?

The Agile Methodology is characterized by its focus on iterative cycles, allowing for flexibility and rapid adjustments throughout the development process. In Agile, developers work in short cycles, called iterations or sprints, where each cycle results in a potentially shippable product increment. This means that feedback can be incorporated continuously, and changes can be made based on user input and testing outcomes.

The iterative nature of Agile enables teams to respond quickly to changing requirements or market conditions, which is a significant advantage over more traditional linear approaches. In Agile, collaboration and constant feedback are emphasized, further driving continuous improvement and adaptive planning, leading to a more successful final product that aligns with user needs.

In contrast, other models such as the Waterfall Model follow a linear and sequential design process, where each phase must be completed before the next begins, thus lacking the flexibility of iterative changes. The Spiral Model does incorporate iterations but is fundamentally focused on risk assessment as its core component. The V-Model, while also a sequential approach, emphasizes verification and validation at each stage rather than offering the iterative benefits that Agile provides.
