The application is delivered through an incremental and iterative process. This means that every 2 to 3 weeks a checkpoint is done with users and stakeholders to demo the part of your application developed during that time. These checkpoints are also the way to cope with business changes. While projects are being developed, business priorities might change, or whole new requirements may show up. Because the detailed analysis, development and testing are done incrementally, if a change or a new requirement comes up that brings significant value to the business that one can exchanged with another of lower business value. During Sprint Development, after each demo, the users are also invited to test the application. Doing so will enable them to provide feedback that will improve the application’s overall quality and usability.
