What is one key feature of the Waterfall method in SDLC?

The Waterfall method in the Software Development Life Cycle (SDLC) is characterized by a sequential design process. This approach is structured so that each phase of development must be completed before moving on to the next. It begins with requirements gathering, followed by design, implementation, verification, and maintenance. Each phase has specific deliverables and a strict timeline. This linear progression allows for clear documentation and defined expectations, making it easier to manage the project's scope and timeline.

The sequential nature of the Waterfall method is advantageous in projects where requirements are well understood in advance and are unlikely to change, as it minimizes the risks associated with late-stage adjustments that could complicate the implementation. It contrasts sharply with more flexible methodologies that allow for overlapping phases or iterative adjustments, emphasizing the importance of completing one phase before proceeding to the next.
