Comparative Study of Different SDLC Models

Abstract: The Software Development Life Cycle (SDLC) refers to a methodology with clearly defined processes for creating highquality software which are cost effective and reliable. This method of software developing process is quite systematic and structural. SDLC defines the framework that has different activities and tasks to be administered during the software development process. Software development process is quite complex, and to do it without any proper planning would be inefficient. So, we use these SDLC models to make the Software development process simple and systematic. There are various software development life cycle models that are used in the software development process, all having their own advantages and limitations. In this paper, we have included six of these SDLC models - Waterfall Model, Spiral Model, V Model, Agile Model, Iterative Model and Rapid Application Development (RAD) Model. These Software Development processes have their own Advantages and Disadvantages, and the main purpose of this paper is to explain these models and know the difference between them.
