Scrum vs Extreme Programming (XP) - Key Differences

Before moving on to other methodologies, here is a comparison between Scrum and Extreme Programming (XP) to understand their terminologies better.

Key Comparisons:

• Sprint in Scrum is equivalent to Iteration in XP.
• Fixed Time Box: Both use a time-boxed approach, usually 1-4 weeks.
• Release: In Scrum, it's just called a release, whereas in XP, it's termed a Small Release.
• Planning: Scrum has Sprint or Release Planning, while XP determines iterations and sprints in an Agile Planning Meeting.
• Roles:
• Scrum's Product Owner is known as the Customer in XP.
• Scrum's ScrumMaster is equivalent to XP's Coach or Agile Project Manager.
• Scrum's Development Team is just called a Team in XP.
• Meetings:
• Retrospective (Scrum) = Reflection (XP) – Both are lessons-learned meetings at the end of an iteration.
• Daily Scrum (Scrum) = Daily Standup Meeting (XP) – A 15-minute meeting covering three key questions.
