Code Reviews That Improve Change Quality

Code review is one of the few engineering practices that can improve a change before it reaches production while also spreading knowledge across a team. It can catch defects, expose unclear assumptions, improve maintainability, and help engineers understand parts of the system they did not write. It can also become slow and frustrating when reviewers focus on preferences, authors submit changes that are too large to reason about, or nobody is clear about what approval means.
