An axiom for ship construction or software development is time spent carefully planning early in the effort will be time not spent refitting the ship when its in the water.

In juxtaposition both methodologies feature up front analysis. But where and how time is spent is drastically different. The waterfall approach is highlighted by an enormous amount of up-front time spent developing specifications. Only after this is complete do developers then tackle the specifications in relative isolation like monks in a monastery. At a time in the distant future the software is presented to the client. |
