Pair programming is a common practice that originated from Extreme Programming (XP), in which two programmers work collaboratively at one computer on the same design, algorithm, or code. The benefits of pair programming on software development are well documented and include improving design quality, reducing defects, lowering staffing risks, enhancing technical skills, and improving team communications [3, 8, 11]. Although pair programming has become increasingly popular, some programmers remain skeptical of pairing.
