This is part of an extensive series of guides about software development. There can sometimes be a gap between what is expected from development and the actual outcomes, which can lead to dissatisfaction and misalignment. This can be remedied by providing clear specifications, holding regular check-ins, establishing feedback loops, and implementing a mentorship program. This comprehensive 2025 guide breaks down key skills, tools, and technologies every full stack developer needs to know. Now that you know why we need a code review, let’s discuss how to conduct one.
Reviewers may lack the tools or expertise to spot inefficiencies in code. To solve this problem, consider using profiling tools, establishing benchmarks, providing performance optimization training, and integrating automated performance analysis tools.

Use peer pressure to your advantage
The diagram below outlines four key rules that can help make code reviews smoother and more productive. This process isn’t just a technical code review checklist – it’s more like an ongoing conversation about the code we write. It has its own rhythm, shaped by collaboration, learning, and shared goals. When developers know their code will be reviewed by a teammate, they make an extra effort to ensure that all tests are passing and the code is as well-designed as they can make it so the review will go smoothly.
How effective are code reviews?
Constructive criticism stands as the backbone of successful code reviews, serving as a catalyst for improvement and learning. Recent findings show that companies with 501 or more employees can be liable for up to $300,000 in damages due to poor evaluation practices, emphasizing the necessity for effective communication. It is essential that responses be specific, actionable, and oriented toward fostering growth. Reviewers should not only indicate what needs modification but also elucidate the reasons behind those recommendations. This rationale assists authors in understanding the purpose of the comments, fostering an atmosphere conducive to improvement. For most developers, over-the-shoulder code reviews are faster and more convenient than pair programming.
- Pairing sessions are popular with development teams because teammates collaborate to identify the most effective solution to a challenge.
- Additionally, it supports defining a checklist for reviewers to follow during code evaluation.
- Essentially, code reviews facilitate more streamlined and effective quality assurance testing.
- AI-based tools must provide insight beyond formatting or syntax.
- Teams that prioritize these practices are well-positioned to thrive in the competitive world of software development.
Choosing the best code review method: 4 types explained
For web development, several files and folders are incorporated. When you start reviewing them, this might look dense and confusing. So, the first step of code review must be splitting the code into sections. Traditional systems like Gerrit and Crucible still have a place, especially for teams with strict compliance needs, but the future is moving toward smarter, faster, and more collaborative reviews. The key is finding the tool that fits your team’s unique needs – one that can integrate seamlessly into your existing workflow, support your scale, and improve team morale.
Improved consistency and maintainability
The biggest game-changer for me was learning to review code in small batches rather than trying to process hundreds of lines at once. I also keep a mental checklist of critical items to look for, and I set a time limit for initial passes-if I can’t understand the changes within 30 minutes, that’s valuable feedback in itself! For simple issues, asynchronous comments work fine, but for complex ones, I’ll schedule a quick call.
- Next on the list of automated code reviews tools, we have Devlo.ai.
- Obtaining a second opinion on the implementation can help identify any potential problems or areas of improvement and help developers understand the code better.
- This particular process is beneficial to both coders as it can lead to fewer errors and improved code quality.
- When code reviews lack clear quality standards, they can become subjective and inconsistent, resulting in potential quality issues.
- With more practice, developers can become proficient at finding the smallest possible increment of a product.
It looks like your team is following some of the best practices for code review. Consider adding some of the tactics that you didn’t check to your team’s process. If you encourage a collaborative culture, developers will feel ownership of their code quality and your team will build trust over time. Conducting reviews on development artifacts like requirements, user stories, and design documents is a good way to ensure that your whole team understands the end goals of a project. Ultimately, incorporating peer reviews into your development workflow can help build high-quality, maintainable software.
Code evaluations are crucial for improving software quality and fostering collaboration among development groups. By inviting peer scrutiny, groups can uncover potential flaws that the original author may have missed, ultimately reducing defect rates significantly. Research indicates that effective evaluations of programming can lead to a reduction of defects by up to 35%, underscoring their importance in the development lifecycle. When you define code review, it is important to explore the tools available for automating the process. These tools check for coding errors and give suggestions on ways of improving the code. However, they are not a substitute for manual reviews, given their shortcomings, which we explore in this article.

Because both sides (Submitter and Reviewer) have clear benefits. what is code review An ambitious developer should seek to work with the best experts and foster his professional growth on a regular basis. There is no better way to increase programming skills than writing lots of code – and, even more importantly, reading excellent code. Hence, regular and precise code review is necessary for any software company, startup or individual developer.
When I’m reviewing code from junior developers on my team, I take the time to explain not just what should change but why it matters. For routine changes from experienced team members, I might focus more on architecture and approach rather than implementation details. Instead of saying “this is hard to follow,” you could say, “consider adding a comment here to explain the reasoning behind this condition-it’s not immediately obvious why it’s needed.” This gives clear direction. Yes, they catch bugs, but some of my biggest growth moments came when a senior developer questioned my approach and showed me a more elegant solution.
The email pass-around method is an older approach to code review, where developers share their code with their teammates for feedback via email. The author typically explains the purpose of the code, attaches the relevant files, and then sends it to one or more reviewers. By discussing potential risks and suggesting secure coding practices during a code review, the development team ensures that the entire codebase adheres to security standards.
It’s a moment where a lot of learning happens, with juniors getting coached on best practices and the project’s specific conventions. Beyond enforcing, these tools offer features like code highlighting, commenting, and suggesting that facilitate collaboration. The reviewer will ensure that everyone adheres to a strict coding style and will use code editors’ built-in helpers to format the code.
This practice creates multiple, informed inputs which, when used for a final estimate always makes that estimate stronger and reliable. By utilizing code reviews earlier on also, it can be made easier for future developers to work on and understand the code that is evaluated. This helps promote knowledge and collaboration among team members along with fostering shared code ownership. Code review is a software quality assurance process where one or more persons or tools systematically examine and evaluate the source code of a program. One or more of the individuals reviewing the code need to read the code and identify any issues within the code. AI-driven tools like Qodo, CodeRabbit, and Greptile are transforming the landscape by automating repetitive checks and providing deeper insights, but they’re not replacing human judgment.
