The V-model is an SDLC model where execution of processes happens in a sequential manner in a V-shape. It is also known as Verification and Validation model. The V-Model is an extension of the waterfall model and is based on the association of a testing phase for each corresponding development stage.
What is another alternative to SDLC?
There are several alternatives to SDLC. The most popular one is the RAD or Rapid Application Development. RAD offers implementation of CASE tools, joint application development, and prototyping. Desirable advantages of RAD are active user involvement, faster approach, and reduced development cost.
