With the development of the Internet, making software is often essential, also it is complicated to succeed in the project’s development. There is a necessity in delivering software of top quality. It might be accomplished through using the procedures of Verification and Validation (V&V) via development processes. The main aim of the V&V has been checking if the created software is meeting the needs and specifications of clients. V&V has been considered as collections related to testing as well as analysis activities across the software’s full life cycle. Quick developments in software V&V were of high importance in developing approaches and tools for identifying possible concurrent bugs and therefore verifying the correctness of software. It has been reflecting the modern software V&V concerning efficiency. The main aim of this study has been retrospective review related to various researches in software V&V and conduct a comparison between them. In the modern competitive world related to the software, the developers of software must be delivering on-time quality products, also the developers should be verifying that the software has been properly functioning and validating the product for each one of the client’s requirements. The significance of V&V in the development of software has been maintaining the quality of software. The approaches of V&V have been utilized in all stages of the System Development Life Cycle. Furthermore, the presented study also provides objectives of V&V and describes V&V tools that can be used in the process of software development, the way of improving the software’s quality.
