What is a characteristic of the Waterfall methodology?

The Waterfall methodology is characterized by its structured approach to project management, which follows a sequential ordering of clearly defined phases. This means that each phase must be completed before moving on to the next, creating a clear path from project initiation through to completion. This methodology is particularly useful in projects where requirements are well understood upfront, allowing teams to define scope, timelines, and budgets with precision before progressing.

Consequently, the Waterfall model minimizes uncertainty by adhering to a predetermined sequence, which makes it easier to manage changes at initial stages but can make it difficult to adapt once certain phases are completed. Alternative methodologies, such as Agile, emphasize flexibility and iterative processes, which are contrary to the rigid structure of Waterfall. This characteristic makes Waterfall suitable for projects with fixed requirements but less effective in dynamic environments where changes are common or expected.
