My attempt to answer this question:

XP is

• Agile methodology driven by developers
• with many prescribed engineering practices

Scrum is

• Agile methodology driven by management
• Simpler framework where engineering isn’t prescribed
• Trust team to do what they need to do
• Can evolve overtime and take on many XP practices incrementally
