System Development Life Cycle (SDLC)

V-Model

It is an extension of the waterfall model, Instead of moving down in a linear way, the process steps are bent upwards after the implementation and coding phase, to form the typical V shape. 

The major difference between the V-shaped model and waterfall model is the early test planning in the V-shaped model.

The Usage:

• For the projects where an accurate product testing is required
• For the small and mid-sized projects, where requirements are strictly predefined
• The engineers of the required qualification, especially testers, are within easy reach.
