Comparative study on agile software development: Software development methodologies are constantly evolving due to changing technologies and new demands from users. Today’s dynamic business environment has given rise to emergent organizations that continuously adapt their structures, strategies, and policies to suit the new environment. Such organizations need information systems that constantly evolve to meet their changing requirements. Though traditional software development methodologies, such as life cyclebased structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It’s a set of best practice that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. Traditional, plan-driven software development methodologies lack the flexibility to dynamically adjust the development process. Agile development is the ability to develop software quickly keeping pace with the rapidly changing requirements. We speculate that from the need to satisfy the customer through early and continuous delivery of the valuable software, Agile software development is emerged. In this paper, we provide a brief comparison of agile development methodologies with traditional systems development methodologies, and discuss the challenges of adopting agile methodologies. A number of software development methods such as extreme programming (XP), feature-driven development, crystal clear method, scrum, dynamic systems development, and adaptive software development are also briefly discussed in this paper.
