Code review analytics displays a table of open merge requests that have at least one non-author comment. The review time is the amount of time since the first comment by a non-author in a merge request. You can use code review analytics to view review metrics per merge request and improve your code review process. - A high number of comments or commits may indicate: - Code that is too complex. - Authors who require more training. - A long review time may indicate: - Types of work that move slower than other types. - Opportunities to accelerate your development cycle. - Few comments and approvers may indicate a lack of available team members. For a video explanation, see [Code review analytics: Faster code review](https://www.youtube.com/watch?v=OkLaWhYkASM). ## View code review analytics Prerequisite: - You must have at least the Reporter role.
