Which model emphasizes continuous feedback in software development?

The Agile Model emphasizes continuous feedback throughout the software development process. This approach is designed to foster collaboration between cross-functional teams and encourages regular updates and iterations based on stakeholder feedback. Agile methodologies, such as Scrum and Kanban, focus on delivering small, functional pieces of software frequently, allowing teams to adapt to changes, refine requirements based on user feedback, and continuously improve the product. This flexibility and responsiveness to change is a core principle of Agile, making it well-suited for environments where requirements may evolve and where customer satisfaction is a priority.

In contrast, the Waterfall Model is more linear and structured, proceeding through distinct phases without the same degree of ongoing feedback. The Iterative Model allows for some feedback through repeated cycles but does not emphasize the real-time, collaborative engagement found in Agile. The Spiral Model incorporates feedback through iterative cycles but is more focused on risk assessment and management, rather than continuous stakeholder involvement like the Agile Model promotes.
