Development team want to choose Agile Development Methodology from either SCRUM or XP(Extreme Programming)

Let us talk about the main difference of SCRUM VS XP Methodology

1. Iteration Length

SCRUM Team

Sprint 2-4 weeks(Recommended 2 weeks)

XP Team

1-2 weeks

2. Features

SCRUM Team

Do not allow changes add into their sprints if sprint has started.

XP Team

can swap feature during the iteration/change priority

3. Priority

SCRUM Team

It depends on user story dependencies, whether fit to sprint or not, team velocity and availability as well. It can be more flexible.

XP Team

work in a strict priority order

4. Practice

Scrum Team

Doesn't describe any engineering practices

XP Team

prescribe engineering practices

Pair programming + test-driven development are the main practices。

About the suggestions, I will recommend to start with SCRUM and invent your own version of XP.

But do not force engineering practices e.g., pair programming or test-driven development

It depends on what good practices fit in your team
