Sequential IT delivery models

In this section two sequential IT delivery models will be explained in more detail: Waterfall and the V model.

Waterfall	V-model
The waterfall model is a sequential (non-iterative) software development process, in which progress is seen as flowing steadily downward (like a waterfall) through the phases of idea/wish/etc., requirements elicitation, analysis, design, coding, testing, deployment (production/implementation), and maintenance.

In the V Model, testing phases are related to corresponding development phases [Koomen 2006]. This means that for every single phase in the development cycle, there is a directly associated testing phase. Read more…
