Paired Programming
Paired programming is an agile software development technique where 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. This collaborative approach aims to improve code quality, facilitate knowledge sharing, and reduce defects through real-time feedback and discussion.
Developers should use paired programming when working on complex or critical code, onboarding new team members, or tackling challenging problems that benefit from multiple perspectives. It is particularly effective in agile environments, for reducing bugs, enhancing design decisions, and accelerating learning, as it combines coding with continuous review and brainstorming.
