Agile software development is an iterative and flexible approach to software development that emphasises collaboration, customer satisfaction, and delivering working software quickly and frequently. Agile development typically involves breaking down the development process into small, manageable tasks or features. These are implemented in short iterations or sprints, incorporating feedback and changes along the way. The goal of agile methodology is to create a responsive and adaptable development process that can quickly deliver value to customers and adapt to changing requirements or priorities.
