Everything about Waterfall model

Modelling software development in sequential phases

The waterfall model is the process of performing the typical software development life cycle (SDLC) phases in sequential order. Each phase is completed before the next is started, and the result of each phase drives subsequent phases. Compared to alternative SDLC methodologies such as Agile, it is among the least iterative and flexible, as progress flows largely in one direction through the phases of conception, requirements analysis, design, construction, testing, deployment, and maintenance. The waterfall model is the earliest SDLC methodology. When first adopted, there were no recognized alternatives for knowledge-based creative work. Wikipedia →
