pariohjelmointi

Pariohjelmointi, also known as pair programming, is a software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently. While reviewing, the observer also considers the "strategic" direction of the work, coming up with ideas for improvements and noting potential problems with the implementation.

Pair programming is a form of peer review and can be used to improve code quality, reduce defects, and promote knowledge sharing among team members. It is often used in agile software development methodologies, such as Extreme Programming (XP), and can be implemented in various ways, including face-to-face collaboration or remotely using tools like screen sharing and instant messaging.

The benefits of pair programming include improved code quality, increased productivity, better knowledge sharing, and enhanced team collaboration. However, it can also have some drawbacks, such as increased development time and potential conflicts between team members. Despite these challenges, pair programming remains a popular and effective practice in the software development industry.
