waterfall

The term evokes a sense of powerful, unidirectional flow and natural grandeur. In its primary sense, it describes a geological feature characterized by gravity-driven descent, often associated with serenity or raw power depending on the scale of the drop.

In professional and technical environments, the term shifts to describe a rigid, sequential methodology. This usage carries a connotation of stability and predictability but is often contrasted with agile methods to highlight its lack of flexibility and the inability to return to a previous stage once it has been completed.
