The history of the waterfall model The waterfall model which is also referred as a linear sequential life cycle model was the first model to be developed. The waterfall model is a sequential design process used in software development processes in which progress is seen as flowing steadily downwards(like a waterfall) through the phases of conception‚ initiation‚ analysis‚ construction ‚testing‚ production/implementation and maintenance. The waterfall model creation originates in the manufacturing
