A Comparative Analysis of Different types of Models in Software Development Life Cycle

The objective of this research was to study, categorize and examine various methods for describing or modeling, as how software systems are developed and to provide solutions in the form of a generalized model which help in producing a correct and high quality software for the companies.  There are various SDLC models widely used for developing software. SDLC models give a theoretical guide line regarding development of the software. SDLC models are very important for developing the software in a systematic manner such that it will be delivered within the time deadline and should also have proper quality. Employing proper SDLC allows the project managers to regulate whole development strategy of the software. Each SDLC has its advantages and disadvantages according to which we decide which model should be implemented under which conditions.
