SOFTWARE DEVELOPMENT LIFE CYCLE MODELS: A REVIEW PAPER

Each application's quality is the finish results of how every step of the life cycle of software development has been managed. In order to achieve a good quality product, multiple teams and strategies are used. Software development is a crucial process that everyone is aware of. However, justice will only be done if all the phases are well involved in their respective ways. Different Software Development Life Cycle (SDLC) models are commonly used for the software development. The SDLC models supply a theoretical guide to software development. The SDLC models that are very important for the systematic evolution of the software in such a way that it will be delivered within the time limit & should be of good quality as well. The proper use of SDLC enables project managers to regulate the software's entire development strategy. Every SDLC has its disadvantages and advantages in deciding which model under which situation should be executed. This paper compares various popular life cycle models such as prototype model, waterfall, prototype, rapid development of applications, V-shaped model, spiral model & incremental model.
