This software development approach focuses on developing software in small iterations to quickly deliver functionality. What is it?

The software development approach that focuses on developing software in small iterations for rapid delivery of functionality is Agile. Agile methodologies prioritize flexibility and customer collaboration, allowing teams to adapt to changes necessary throughout the development process. This iterative approach enables teams to deliver working software more frequently, often in cycles known as sprints, which can last anywhere from a couple of weeks to a month.

Agile practices emphasize the importance of regular feedback and continuous improvement. Teams work closely with stakeholders to ensure that the software being developed meets their needs and can adjust quickly based on this input. This leads to faster delivery of valuable features and improvements over time, as opposed to a more linear approach where all requirements would be set upfront, limiting the ability to respond to changes effectively.

In contrast, other methodologies such as Waterfall typically follow a sequential design process, which can lead to longer development cycles and less flexibility to accommodate changes. Rapid Release focuses on quickly pushing out updates, but it may not necessarily incorporate the same iterative and collaborative principles that define Agile. Meanwhile, PPV, or Production Planning Variants, is not relevant in this context as it does not represent a software development methodology in the same way Agile does.
