Scrum and Extreme Programming
Incorporating XP practices into Scrum
Scrum and Extreme Programming (XP) are both Agile frameworks that share similar values but differ in their implementation approaches. Scrum is a lightweight framework designed to help teams deliver complex products iteratively and incrementally. It defines three roles (Product Owner, Scrum Master, and Developers), five events (Sprint, Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective), and three artifacts (Product Backlog, Sprint Backlog, and Increment). Scrum operates in fixed-length iterations called Sprints, typically 1-4 weeks long. The Scrum Master serves as a servant-leader who helps everyone understand and follow Scrum practices while removing impediments. Scrum is framework-focused, providing boundaries within which teams can address complex problems. Extreme Programming complements Scrum by focusing on specific engineering practices. While Scrum describes "what" to do, XP often provides the "how" through technical practices. XP emphasizes practices like pair programming, test-driven development (TDD), continuous integration, simple design, and refactoring. XP also values small releases, collective code ownership, coding standards, and sustainable pace. Many Scrum teams incorporate XP practices to enhance their technical excellence. For example, a Scrum team might use XP's pair programming and TDD practices to improve code quality while following Scrum's framework for planning and delivery. In PSM I certification, understanding Scrum as its own complete framework is essential, while recognizing how complementary practices from other approaches like XP can enhance—but are not required for—effective Scrum implementation. Scrum deliberately leaves implementation details to the team, creating space where XP practices can fit naturally if the team chooses to adopt them.
