The Waterfall method should be thoroughly analyzed to know whether it is suitable for the project or not. Accommodating changes is very hard.

The analysis can be done by considering the limitations of the Waterfall project. Weaknesses: In real life situations, it is pretty hard to abide by the “no change to the sprint backlog” rule. 5. The Waterfall methodology—also known as the Waterfall model—is a sequential development process that flows like a waterfall through all phases of a project (analysis, design, development, and testing, for example), with each phase completely wrapping up before the next phase begins.
