1. A software development team at LogicaCMG adopted Extreme Programming (XP) practices to address issues with their mature product set such as high costs, complex configuration management, and lack of innovation due to long development cycles and QA testing. 2. They implemented XP practices like offshore development for maintenance, intensive training, iterative development, test-first practices, continuous integration, and onsite customers. 3. This resulted in benefits like releasing their first new product within 3 months, 50% fewer defects, test cycles reduced from 2 months to zero, and delivering working software frequently which allowed for continuous feedback.
