Waterfall Model - Model

Model

In Royce's original waterfall model, the following phases are followed in order:

  1. Requirements specification
  2. Design
  3. Construction (implementation or coding)
  4. Integration
  5. Testing and debugging (validation)
  6. Installation
  7. Maintenance

Thus the waterfall model maintains that one should move to a phase only when its preceding phase is completed and perfected. Various modified waterfall models (including Royce's final model), however, can include slight or major variations on this process.

Famous quotes containing the word model:

    It has to be acknowledged that in capitalist society, with its herds of hippies, originality has become a sort of fringe benefit, a mere convention, accepted obsolescence, the Beatnik model being turned in for the Hippie model, as though strangely obedient to capitalist laws of marketing.
    Mary McCarthy (1912–1989)

    Socrates, who was a perfect model in all great qualities, ... hit on a body and face so ugly and so incongruous with the beauty of his soul, he who was so madly in love with beauty.
    Michel de Montaigne (1533–1592)

    I’d like to be the first model who becomes a woman.
    Lauren Hutton (b. 1944)
