Outsourcing software development to China - V Software LifeCycle

V Software LifeCycle Method

The V model shown below is similar to the Waterfall, but also shows the relationship between design and testing activities. The lines with arrowheads are test plans. For a system with safety aspects assessment and validation may have to be carried out by independently.

'V' Lifecycle Model

Waterfall and V life cycles assume that one stage is complete before the next starts. Completion is justified by a verification processes. The Waterfall and V are good for management cost control and progress reporting but extend project duration when it is difficult to identify requirements. It also does not facilitate the reuse of existing code elements. Waterfall and V life cycles work best when the supplier has already produced similar products for other customers. The V life cycle shares the limitations that are listed on the Waterfall model page.
