Working with a partner to develop code. The Agile practice of pairing involves two people working together at the same computer to develop code. The two people may be two developers, a developer and a tester, or any other combination of roles. The goal of pairing is to increase collaboration, knowledge sharing, and quality, and to reduce the risk of errors and delays.
Pairing is based on the principle that two heads are better than one, and that working together can help to uncover problems and opportunities that might otherwise be missed. By working side-by-side, the two people can share ideas, provide feedback, and catch problems early in the development process, leading to a faster and more efficient development cycle.
While pairing is not suitable for all situations, it can be a valuable technique for increasing collaboration and quality in Agile development. Pairing can be especially useful when working on complex or challenging problems, or when introducing new team members to a project.
