We build Google’s code review tool for Google software engineers.
A code review is a process where a software engineer asks co-workers to review her code changes. They usually check the quality and structure of the source code, and appearance, such as formatting rules. Code reviews at Google may lead to long discussions between two or more engineers and include statuses like
- LGTM (“looks good to me”)
- “needs more work”
- FYI (“for your information”)
Code review is a central part of collaborative, high quality software development.
