By adopting an iterative software development, agile methodologies help and allow developers to adapt to the changes in the system requirements quickly. Interactions and communications between team members enable them to make pure decisions and act on the decisions quickly instead of having to wait for correspondence. Additionally Corey Davis Hat , agility helps the developers reduce artifacts that have little value on the final system. Therefore, by adopting the agile methodology, the developers can devote software development resources to the production of the software while completing the development of the software sooner (Ambler Rashaan Evans Hat , 2002). Role of Agile Methodology Software development has become a highly sophisticated area with countless variables which impact the system being developed. All software systems cannot be comprehensively built using mathematical or physical certainty. This is where the role of agile methodology comes to play. But what is the main role of agile methodology in the system development? According to Edmonds (1974) the main role of agile is increasing efficiency in the process of system development by incremental and iterative development, embracing change, empirical process of project management Delanie Walker Hat , and by lean thinking. Incremental and Iterative Development Agile methodology brings the simple ability of the developers to revisit the steps of system development. This dramatically improves the efficiency of the project. The way in which project developers revisit steps of the system development is referred to as incremental and iterative development (IID). Agile methodologies split the system development life cycle into iterations or increments where each addresses each of the traditional steps of system development. Embracing Change
