Guide to Pair Programming in PMI-ACP XP
Pair Programming is an important technique in Extreme Programming (XP) fundamental to Agile methodologies.
What is Pair Programming?
Pair Programming is a programming practice where two developers work on the same codebase at the same machine at the same time. One person writes the code, called the 'driver', and the other person reviews the code written by the driver - called the 'navigator'. This leads to higher code quality by reducing mistakes and improving design.
Why is it important?
Pair programming provides multiple benefits: enhancing code quality, promoting team collaboration, facilitating knowledge sharing, and decreasing software defects.
How does it work in PMI-ACP XP?
In the context of PMI-ACP XP, pair programming is an integral part of the development process. In this environment, collaboration is valued over contract negotiation, thus the pair programming methodology is advantageous.
How to answer questions in an exam?
When answering exam questions relating to pair programming, remember the core principles: collaboration, code sharing, real-time problem solving, and knowledge transfer. Understand the benefits and drawbacks of the methodology, and relate it to the context of Agile and Extreme Programming.
Exam tips:
- Always remember the roles of the driver and the navigator in pair programming.
- Understand the benefits of pair programming in an agile environment.
- Be aware of situations where pair programming might not be the most efficient use of resources.

Pair Programming practice test
Pair Programming is a technique of XP where two developers work together at a single workstation, often physically sitting side-by-side sharing a single computer. One developer, the 'driver', writes the code while the other, the 'observer' or 'navigator', reviews each line of code as they are typed in. The developers switch roles frequently. This practice encourages communication, reduces coding mistakes, promotes collective code ownership, and ensures high-quality code.
