It is expected that the different experiences of the two members of one team would provide more efficient resources to write the codes. But pair programming adoption is 13% higher among teams with successful agile development when compared to teams with unsuccessful agile practices.

These five fundamental values provide the foundation on which the entirety of the Extreme Programming paradigm is built, allowing the people involved in the project to feel confident in the direction the project is taking and to understand their personal feedback and insight is as necessary and welcome as anyone else. Each iteration has its own planning, design, coding, testing, and release… Pair Programming This practice requires two programmers to work jointly on the same code. Simplicity: We will do what is needed and asked for, but no more. Pair programming isn’t new; it’s been around the software development industry for decades.
