Which of the following methodologies emphasizes iterative development?

The Agile methodology emphasizes iterative development, which is a core principle that sets it apart from other project management approaches. In Agile, projects are divided into small, manageable units called iterations or sprints, usually lasting a few weeks. This iterative process allows teams to continuously assess their work, incorporate feedback, and adapt to changing requirements throughout the project lifecycle.

The focus on iterative development facilitates flexibility and responsiveness, enabling teams to refine their solutions based on customer input and changing conditions. This adaptability is particularly beneficial in environments where requirements are expected to evolve or are not fully understood at the project's outset. Additionally, Agile practices promote collaboration among team members and stakeholders, ensuring that the product aligns closely with user needs and expectations.

In contrast, other methodologies like the Waterfall model follow a linear, sequential approach where each phase must be completed before the next begins, limiting iteration. The Critical Path Method focuses on scheduling project tasks, while Lean methodology aims at maximizing value by minimizing waste, without the same emphasis on iterative cycles as seen in Agile.
