Agile Software Development: A Case Study of Web Application
. D. T. T. Vijaya Kumar & Ms. M. Sowmyavani
By Mr
MCA Sree Vidyanikethan Engineering College
Abstract - Agile methodology is an approach used for the development of a project which helps to
respond to the unpredictability of building software through incremental, iterative work cadences.
These methodologies are used to deal with the situations where the waterfall model fails. The biggest
drawback of waterfall model is that it assumes that every requirement of the project can be identified
before any design or coding occurs [1]. In this paper we are specifying the differences in the
development of a project by using the Agile Methods: Extreme Programming (XP) and Scrum
through a case study on Women’s Era (WE- A State Level Women Development and Support).
Keywords : Agile Methodology, Extreme Programming (XP), MVC –Design Pattern, Sprin t, Backlogs,
