From Peer Review to Pair Programming

[article]

Summary
Introducing a peer review or pair programming practice into an organization (or project) can be an effective way to improve quality while minimizing culture change. Peer reviews in the form of a code review can be effective way of identifying defects and therefore improving application quality. When establishing a peer review practice, the following can help to ensure success: establishing coding standards; identifying appropriate level of peers; establishing a closed loop defect system to ensure corrective action; and providing requirements and/or defect records to understand why a particular code artifact is being created, changed, or fixed. Pair programming can also be an effective way of identifying defects and in solving problems, thereby improving application quality. When establishing a pair programming practice, the following can help ensure success: identifying appropriate level of peers; finding people that work well together; and focusing on problem solving work. Once you have started either (or both) practices, continually monitor its effectiveness with both metrics and feedback from the people involved for continuous improvement.
