The evolution of agile software management results from challenges with legacy development methodologies such as stagewise, waterfall, and spiral. The popularity of agile software development methodologies has increased worldwide. The critical processes in agility are iterative, timebound cycles that accommodate change and enable development teams to manage uncertainty and unforeseeable changes. The most widely used agile development approaches are Scrum, extreme programming, feature-driven development, kanban, and the crystal family of development methods. Agile provides an approach to solving the issues associated with the rigidity of legacy methodologies that hindered the benefits of flexible iterations.
The agile development methodology embraces changing requirements often not fully understood when the project begins. Changing software requirements typically driven by the customer can adversely affect the quality of the final software product. Many organizations embrace the agile methodology in response to the demand for quick delivery, reduced costs, and increased project flexibility. The popularity of the agile software development approach has reduced time to market, increased corporate competitive advantage, and resulted in higher quality satisfaction. The agile approach is well suited for managing uncertainty in software development, and the process offers significant benefits that include knowledge learning, employee satisfaction, confidence from feedback, and scalability. The agile methodology addresses the need to provide working software to customers quickly and adapt to changing requirements.
