What is the Difference Between Extreme Programming and SCRUM?

Extreme Programming (XP) and Scrum are both Agile project management methodologies used in software development, but they have different focuses and practices. Here are the main differences between the two:

1. Focus: Scrum focuses on project management and teamwork, while XP focuses on code quality and individual programmers' work.
2. Iteration Length: Scrum teams typically work in iterations (called sprints) that are from two weeks to one month long, while XP teams typically work in iterations that are one or two weeks long.
3. Priority Order: In Scrum, the team determines the sequence in which the product will be developed, while in XP, the team has to follow a strict priority order or pre-determined priority order.
4. Emphasis on Software Engineering Practices: Scrum does not put emphasis on specific software engineering practices that developers should use, while XP emphasizes programming techniques that developers should use to ensure a better outcome. XP is known for its strong engineering practices, such as pair programming, simple design, and continuous testing.
5. Change Management: Scrum teams do not allow changes into their sprints once the sprint planning meeting is completed and a commitment is made to deliver a set of product backlog items. XP teams, on the other hand, are more amenable to change within their iterations.

In summary, Scrum and XP are both popular Agile methodologies in software development, but they differ in their focus, iteration length, priority order, emphasis on software engineering practices, and change management. While Scrum focuses on project management and teamwork, XP focuses on code quality and individual programmers' work.

Comparative Table: Extreme Programming vs SCRUM

Extreme Programming (XP) and Scrum are both Agile software development methodologies, but they have some key differences. Here is a table comparing their characteristics:

Both methodologies have common concepts of iterative development, working software, and frequent releases. However, Scrum focuses more on management, while XP focuses on programming, coding, and test-driven methodology. In contrast to XP's strict engineering practices, Scrum relies on self-organization.
