Extreme Programming for service-based application development architecture

The Rational Unified Process is a complete software-development process framework that comes with several out-of-the-box instances. The process of developing of new software product versions has speed up rapidly. The necessity of flexible and particularly prompt responses to the changes triggered off genesis of new technologies, software architectures and methodologies. The Service Oriented Architecture (SBA) allows defining services operation environment, web services then form one of the available technologies for SBA realization. The software development limits the possibilities of adapting the development process to the changes and up-to-date requests. This problem might be solved by adoption of Extreme Programming (XP).
