waterfall model
(foldoc) | Waterfall Model
A software life-cycle or product life-cycle
model, described by W. W. Royce in 1970, in which development
is supposed to proceed linearly through the phases of
requirements analysis, design, implementation, testing
(validation), integration and maintenance. The Waterfall
Model is considered old-fashioned or simplistic by proponents
of object-oriented design which often uses the {spiral
model} instead.
Earlier phases are sometimes called "upstream" and later ones
"downstream".
Compare: iterative model.

Systems", Proceedings of IEEE WESCON, August 1970].
