“An Agile software development technique in which two programmers work together at one workstation. One types in code while the other reviews each line of code as it is typed in. The person typing is called the driver. and the person reviewing the code is called the observer or navigator. The two programmers switch roles frequently.” (Wikipedia)

Pair programming is one of the original 12 Extreme Programming (XP) practices. As counter-intuitive as it may seem to the uninitiated, pair programming is more productive than two individuals working independently on separate tasks.
