Each phase must be completed before the next phase begins. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical v shape. The v model is an enhanced version of the classic waterfall model whereby each level of the development lifecycle is verified before moving on to the next level. It also verifies that the codes are efficient and adheres to the adopted coding standards. This is a major exception and the v model does not support the broader view of testing as a continuously major activity throughout the software development lifecycle. V model is now one of the most widely used software development processes. The decision to use the simulation continue reading. The v model addresses software development within a project rather than a whole organization. In this each phase of sdlc must be completed before the next phase starts.
