Extreme Programming (XP) • Exploration – Stories

• Planning

– Prioritize Stories

• Transition to release

– Analysis-design-testing Feedback continuous integration

• Production Phase – Small releases

• Maintenance phase – Updated Releases

• Death phase – Final release THUS XP covers SDLC from Requirements to System testing
