Pair Programming

XP practice in which two developers work together at one workstation: a driver who writes code and a navigator who reviews.

Definition

Pairing improves quality, spreads knowledge, and reduces defects; partners switch roles frequently.

Example

The navigator spots an edge case while the driver writes a function.

Exam tip

Pairing is a knowledge-sharing and quality practice, not a waste of capacity.
