FAQ
1. How long should a code review typically take?
The ideal duration for a code review depends on the complexity and size of the changes, but research suggests that reviewing more than 200-400 lines of code in one sitting leads to diminishing returns in defect detection. For optimal effectiveness, aim to keep individual review sessions under 60 minutes, focusing on smaller, more manageable chunks of code. Larger changes should be broken down into smaller, logically separated pull requests. This approach improves reviewer focus and allows for more thorough feedback. Some organizations establish service-level agreements (SLAs) for reviews, typically expecting initial feedback within 24-48 hours of submission to maintain development momentum.
2. How can we make code reviews more constructive and less confrontational?
To make code reviews more constructive, focus on the code rather than the person who wrote it, use a questioning approach rather than making demands, and provide clear reasoning for suggested changes. Establish team norms that emphasize learning and improvement rather than criticism. Incorporate positive feedback alongside suggestions for improvement, and ensure reviewers have been trained in constructive communication techniques. Using automation for style and formatting issues can also remove potential friction points. Creating a psychologically safe environment where team members feel comfortable discussing technical decisions openly is crucial for productive code reviews.
3. What’s the ideal number of reviewers for a code change?
Research and industry experience suggest that one to two reviewers typically provide the optimal balance between thorough feedback and review efficiency. Having too many reviewers can lead to diffusion of responsibility, where everyone assumes someone else will catch issues, while having too few may miss important perspectives. For critical systems or particularly complex changes, you might include additional specialized reviewers focusing on specific aspects like security or performance. Consider the “two eyes” principle as a minimum standard—ensuring at least one person besides the author has examined the code before it’s merged—while being flexible based on the change’s scope, risk, and organizational requirements.
4. How do we balance code review thoroughness with development speed?
Balancing thoroughness with speed requires strategic approaches to the review process. Implement automated checks for style, formatting, and basic quality issues to free reviewer time for more complex considerations. Prioritize review areas based on risk and impact, focusing more attention on critical code paths or security-sensitive functionality. Consider adopting a tiered review approach where routine changes receive lighter reviews while critical components get deeper scrutiny. Encourage incremental development with smaller, more frequent pull requests that are easier to review quickly. Finally, establish clear expectations around review turnaround times and regularly measure and optimize your review process using metrics like cycle time and defect escape rate.
5. How should new team members be integrated into the code review process?
Integrating new team members into code reviews requires a gradual, supportive approach. Start by having them review simpler changes alongside an experienced team member who can guide them through the process and explain the rationale behind feedback. Provide them with review checklists and documentation about codebase conventions and architectural principles. Assign them as secondary reviewers initially, allowing them to observe and learn without blocking progress. Give constructive feedback on their reviews to help them develop their communication skills. As they gain confidence, gradually increase the complexity of the code they review. This approach, similar to onboarding buddy systems, helps new team members build confidence while contributing meaningful value to the review process.
