The SDLC does not conclude until all the phases have been successfully fulfilled. Development and testing processes are carried out based upon the choice of development methodology. This is a system development method in which needs and requirements of the user are not locked and the user can make changes in the system developed by the developer. The V-model, or Verification and Validation model, is somewhat like the waterfall model, and it requires a defined timeline because the testing stage is incorporated into each step of product development. Below is a brief explanation and how they relate to the SDLC. The fundamental idea of iterative development is the following: instead of one long sequence of actions, the entire product life cycle is divided into several minicycles (iterations). Agile methods, by contrast, may produce a backlog of tasks to be performed. The software development lifecycle (SDLC) is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The design stage creates a basis for the development step and can relatively decrease the time spent on the following stages of SDLC. Prototyping is highly validated these days since at its base lies the idea of creating an early sketch of any newly introduced software or application.
