Peer Review
Peer review is a collaborative software development practice where team members systematically examine each other's code, designs, or documentation to identify defects, improve quality, and share knowledge. It involves structured feedback sessions, often using tools or formal processes, to catch errors early and ensure adherence to coding standards. This methodology enhances code maintainability, reduces bugs in production, and fosters team learning and consistency.
Developers should use peer review to improve code quality, catch bugs before deployment, and ensure consistency across a codebase, especially in team environments or for critical systems. It is essential in agile development, open-source projects, and regulated industries (like finance or healthcare) where reliability and security are paramount. Regular peer reviews also help junior developers learn best practices and senior developers stay aligned with team standards.
