Abstract
The problem of changes in software development is a complex one, and it is almost impossible to avoid it. Indeed, the continuous evolution of the real world causes frequent changes in functional requirements, which entail frequent modifications to the software, yielding a gradual decay of its overall quality. To tackle this problem, two methodologies have been proposed: waterfall methodologies, and incremental/iterative methodologies. The formers try to prevent changes, whereas the second ones consider system development as a step by step process.
