WATEERFALLVs V-MODEL Vs AGILE: A COMPARATIVE STUDY ON SDLC

Abstract

Organizations that are developing software solution are faced with the difficult choice of picking the right software development life cycle (SDLC). The waterfall model is a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases. The V-model represents a software development process which may be considered an extension of the waterfall model. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical V shape Agile Modeling is a practice-based methodology for modelling and documentation of software-based systems. It is intended to be a collection of values, principles, and practices for modelling software that can be applied on a software development project in a more flexible manner than traditional Modelling methods. This comparative summarizes the steps an organization would have to go through in order to make the best possible choice.
