It is widely acknowledged, that removing software defects is much cheaper in the early stages of the development cycle than in the later phases, as shown on the graph below. This is why at Microquery Limited we always assign a QA team to the project right at the beginning. Quality cannot be added at the end of the project, it needs to be verified and validated continuously. In fact UK research shows that one of the three main reasons for the success of a project is maintaining a high level of quality through its duration.
