Unveiling the Distinctions: Software Craftsmanship vs Extreme Programming
Scrum and Extreme Programming (XP) are Agile methodologies aiming to deliver working software iteratively and incrementally. However, there are some critical differences between the two.
Scrum is a framework for managing and completing complex projects. It is based on the principles of transparency, inspection, and adaptation. Scrum teams work in sprints, which are usually 1-4 weeks long, during which they plan, execute, and review the work that needs to be done. Scrum has specific roles, ceremonies, and artifacts, such as the Product Owner, Scrum Master, Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
On the other hand, Extreme Programming (XP) is a set of practices and values for software development. It emphasizes communication, simplicity, feedback, and courage. XP teams work in a highly collaborative environment and use pair programming, continuous integration, and test-driven development to deliver operating software quickly and efficiently. XP also has specific practices such as the Planning Game, Whole Team, Small Releases, Metaphor, Simple Design, and Sustainable Pace.
In summary, Scrum is a framework for managing projects, while XP is a set of practices for software development. Scrum has specific roles, ceremonies, and artifacts, while XP focuses on pair programming, continuous integration, and test-driven development. Scrum is more prescriptive, while XP is more flexible, allowing teams to adapt and tailor the process to their needs.
