Distributed Agile Software Development
Agile software development refers to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. Agile methods works very well in highly dynamic IT environment.
The main objective is to develop software that satisfies the customers, through continuous delivering of working software, and getting feedback from customers about it. The second principle is accepting changes in requirements at any development stage, so that customers would feel more comfortable with the development process. The third principle is the cooperation between the developers and the customers (business people) on a daily basis throughout the project development. The last principle is developing on a test-driven basis; that is to write test prior to writing code. A test suite is run on the application after any code change.
