Tips For Making Code Review Checklist More Effective

Let’s not merely skim the surface of code review checklist; let’s amplify it’s impact! To ensure that code reviews are productive and not a time sink, it’s essential that we follow some effective practices. So, here in this section, we are going to suggest eight valuable tips to enhance the effectiveness of your code review.


1. Understand Code Review Objectives

Imagine you’re an architect designing a bridge. Understanding its purpose ensures you craft a structure that’s strong and safe. Similarly, grasping the goals of a code review clarifies what to focus on.

Are you hunting for bugs, assessing performance, or enhancing readability? By keeping these objectives in mind, you can approach code reviews with a more holistic mindset and ensures everyone’s on the same page.

Understanding the purpose of a code review helps you provide more valuable feedback. As, instead of merely pointing out errors, you can now offer suggestions for improving code structure, enhancing readability, and adhering to the coding standards.


2. Pretest Code Before Reviewing

Running tests and conducting preliminary checks can save valuable time for both you and your colleagues. Submitting code that hasn’t been pretested can lead to frustration for reviewers and may result in delays in the review process.

So, pretesting your code before presenting it for review not only helps catch simple yet critical errors but also showcases your commitment to quality. It’s like serving a beautifully decorated cake that tastes as good as it looks.


3. Cap Reviews at 60 Minutes

Ever heard of diminishing returns? Spending excessive time on a review can lead to exhaustion and reduced effectiveness. Set a time limit of around 60 minutes per review as reviewers are more likely to provide thorough feedback when they are fresh and engaged.

This time limit encourages focus, ensures that reviewers remain attentive, and prevents unnecessary delays. This approach also helps to create a sense of urgency, prompting reviewers to prioritize the most critical aspect of the code.


4. Limit to 400 Lines Checked

Imagine you’re proofreading a novel. Scanning hundreds of pages at once might make you miss errors. Similarly, reviewing an extensive code-base in a single setting can be overwhelming. So, limit your code reviews to around 400 lines to make it more manageable and effective.

This bite-sized approach ensures thorough examination and attention to details. It also results in more frequent code reviews, leading to a better code quality overall.


5. Constructive Feedback, Not Harmful

If feedback is used wisely, it can heal and enhance. Used carelessly, it can harm. Constructive feedback highlights areas for improvement without demotivating the developer. Instead of saying “This is terrible,” consider “Here’s a way to make it even better.” Remember, our goal is to improve the code, not to criticize the developer. So, focus on the code, not the person. Point out issues with clarity and offer solutions or suggestions that help developers learn and grow.


6. Involve Everyone in Reviews

Code reviews should involve everyone on the team, regardless of seniority or role. Diverse perspectives bring fresh insights. Encourage junior developers to participate as reviewers, too. Their questions can often uncover hidden issues. For example, a junior developer might ask a seemingly basic question during a review, such as, “Why did you choose this data structure?”

This question can lead to a discussion that reveals a more efficient alternative, benefiting the entire team. Involving everyone promotes knowledge sharing and ensures that reviews are not limited to just a few experts. It also helps distribute the responsibility and benefits of code reviews across the entire team.


7. Automate for Efficiency

Automation tools can significantly streamline the code review process. Use static analysis tools, linters, and continuous integration systems to catch common issues automatically. This allows reviewers to focus on higher-level concerns. Automation reduces the burden on reviewers by handling routine checks.

It also ensures that code adheres to coding standards consistently, saving time and effort. For example, if your team uses a linter that automatically flags code style violations, reviewers don’t have to perform manual checks for indentation or naming conventions, the linter handles these tasks.


8. Prioritize Standards Over Personal Preferences

Think of coding as a language. Just as adhering to grammar rules ensures clear communication, adhering to coding standards ensures reliable software. Prioritize these standards over personal preferences to create consistent, maintainable code.

Avoid nitpicking over minor style choices unless they significantly impact readability or maintainability. Prioritizing standards avoids time wasted on trivial debates during reviews. It keeps the focus on code quality and functionality.
