Pair Programming

Pair Programming refers to the practice whereby two programmers work together at one computer, collaborating on the same design, algorithm, code, or test. The pair is made up of a driver, who actively types at the computer or records a design; and a navigator, who watches the work of the driver and attentively identifies problems, asks clarifying questions, and makes suggestions. Both are also continuous brainstorming partners [Laurie Williams, computer science professor at North Carolina State University].

The two partners regularly switch roles, making them equal partners. This can work for programmers young and old, novice and expert. Pair programming is considered an industry best-practice, leading to better results in less time.
