CAPM Agile Frameworks and Methodologies Practice Question
In Extreme Programming (XP), which practice involves a customer representative working closely with the team to define and prioritize features, providing continuous feedback throughout the project?
⚠ Common exam trap
Watch out — candidates often confuse technical XP practices like TDD or continuous integration with the customer-centric practice of having an on-site customer.

Correct answer & explanation
✓
On-site customer
In XP, the on-site customer practice embeds a real customer within the team to define and prioritize features, answer questions, and provide continuous feedback. This practice ensures that the team has immediate access to business expertise and can adapt quickly to changing requirements. The other practices listed are technical or team-focused and do not fulfill this customer-facing role.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Test-driven development
Why it's wrong here
Test-driven development (TDD) is an XP practice where tests are written before code. It improves design and ensures that code meets requirements. While it provides feedback on code correctness, it is a developer practice and does not involve a customer representative in defining or prioritizing features.
- ✗
Continuous integration
Why it's wrong here
Continuous integration is an XP practice where code changes are integrated and tested multiple times a day. It ensures that the software remains in a working state and reduces integration problems. However, it does not involve a customer representative defining or prioritizing features; that is the role of the on-site customer.
- ✗
Pair programming
Why it's wrong here
Pair programming is an XP practice where two developers work together at one workstation, but it does not involve a customer representative. It focuses on code quality, knowledge sharing, and continuous review. While it supports feedback, it is not the practice that directly integrates the customer into the team.
- ✓
On-site customer
Why this is correct
The on-site customer practice in XP requires a real customer to be available full-time to the team. This person defines user stories, prioritizes them, and answers questions immediately. This continuous involvement ensures the team builds what the customer needs and receives rapid feedback, which is a core XP value.
