What is a key benefit of iterative software development models?

A key benefit of iterative software development models is that they provide flexibility to change throughout development. This approach allows teams to revisit and revise project requirements in response to user feedback and evolving project needs.

Iterative models, such as Agile, involve developing software in small, manageable increments, which encourages frequent reassessment of project priorities and requirements. As the development process unfolds, teams can adapt to new insights and changing circumstances without being locked into a fixed plan established at the project's outset. This responsiveness not only enhances the final product through continuous improvement but also fosters better alignment with stakeholder expectations as developers are more equipped to address issues as they arise.

In contrast, options that suggest detailed upfront planning or defining all requirements at once disregard the inherent uncertainty and complexity of software projects, which often evolve as development progresses. While reducing total project duration can be a benefit in some contexts, it is not guaranteed and does not capture the essence of iterative development's adaptability and responsiveness.
