Having a code review policy is like having speed limit signs on the motorway. Without enforcement, you can make the argument that speed limits don’t save lives because everyone drives as fast as they can anyway. Same thing for code review. If it’s not policed by management, then it does nothing. I saw one place that would send alert emails if a commit was approved too fast, assuming that someone must have had it insta-approved by a friend as a favour.
