SCRUM has been made an everyday term by Jeff Sutherland and you are often confronted with it. Certain elements from SCRUM, such as the Kanban Board and the daily standup meetings, were very well received – even outside of IT. But like SCRUM, Extreme Programming (XP) is also very popular with agile projects. However, it is needed more by pure software development teams because it is the Agile Framework with the most non-negotiable specifications. For example, regarding engineering practices for software development. It has clear quality requirements and sets its focus there.
SCRUM and XP share basic concepts such as iterative development, delivering functional software as quickly as possible, release and iteration planning in sprints, daily standups, reclectation and improvement. Many consider both to be the same framework and admittedly, it is also difficult to distinguish them. Especially when one software team makes SCRUM and the other in the same department XP.
But as mentioned at the beginning, there are also significant differences:
In summary, when it is decided whether companies want to focus more on self-organization and give developers leeway (SCRUM) or clear engineering practices, companies need to decide whether to focus more on self-organization (SCRUM), but also want to have more reviews but also predetermined sequences of priorities (XP).
However, XP has clear guidelines and most rules are non-negotiable. So it may make sense for project teams that have only recently been working together and tend to be more inexperienced to start with XP. Once the team has gained enough experience and takes the engineering practices for granted, you can switch to a professional SCRUM team.
