How AI Code Review Reclaims Your Team's Time

Oct 5, 2023


In the era of building and improving products fast, engineering managers encounter fresh challenges that render traditional strategies outdated. The amount of time spent trying to make sure that teams not only build products fast, but also without breaking too much stuff or introducing security vulnerabilities, is significant.

One of the most time-intensive tasks involves conducting code reviews – these crucial checkpoints serve as guardians, shielding your codebase from potential chaos. Additionally, code reviews are an essential part of compliance; which is often a requirement when working in an enterprise. Despite their significance, they can also turn into obstacles, occasionally stalling the deployment process. The question at hand is: How can we navigate through this impediment while upholding top-notch code quality?

Introducing AI-powered code reviews! Picture your team's pull requests getting reviewed as soon as they're made. That's the magic of AI code review tools. For teams, this means you don't have to wait for hours to get feedback. Reviewers can still offer more feedback later. It also means your teams can stay on track, creating and releasing features, without the usual delays of waiting for code reviews.

We'll discuss the regular stages of software projects and the impact of AI code reviewers like CodeRabbit in this digital era. You'll gain a detailed insight into how these tools are changing the game, making code reviews faster, smarter, and surprisingly, more human-like.

The Typical Software Lifecycle Process

Ah, the software lifecycle—the process where we turn ideas into lines of code that build our products. If you're an engineering manager, you're already well-versed in the dogma: planning, coding, testing, deploying, and maintaining. It's a continuous cycle with its own set of challenges.

So, where do code reviews fit into this? They help us make sure that we know what we are shipping to our users by having different people cross-check each other's work. You can't skip them; they serve as a critical validation point, ensuring that the code you're churning out works and is optimized and secure. Code reviews are the gatekeepers that scrutinize your code before it gets the VIP pass to merge into the main branch.

But let's be real. Traditionally, this process has been manual, slow (with delays between opening pull requests and having them reviewed), subjective, and, yes, prone to human error. But if there's anything the advent of AI code review tools shows us, there is an opportunity to reclaim some of the time we spend doing code reviews.

In the upcoming sections, we'll dive deeper into how the traditional and often cumbersome process of code reviews is changing with AI.

The Traditional Code Review Method

In the conventional approach, code reviews followed this pattern: one developer wrote the code and then passed it on to another person for evaluation. The reviewer took their time to meticulously inspect the code submitted by the developer. This involved examining lines of code and making notes, comments, questions, and identifying any problems. This process typically unfolds as follows:

  • A developer creates a Pull Request (PR) and outlines the changes made, requesting a review.

  • The reviewer, who might be another developer or an engineering manager, assesses the code, looking for specific aspects such as:

    • Ensuring that the PR changes align with the scope of the associated ticket(s).

    • Confirming the accuracy of business logic implementation.

    • Maintaining or improving code quality by reverting unnecessary changes and upholding code quality standards.

    • Verifying that the changes do not introduce security vulnerabilities.

  • The reviewer either approves or rejects the PR.

  • If approved, the PR can be merged.

  • If rejected, the reviewer provides feedback on the required updates for approval.

This process has been a fundamental part of modern coding. It relies on the availability of both the reviewer to provide feedback and the developer to make changes based on that feedback.

However, manual code reviews can be likened to a risky game with your code's quality, somewhat resembling playing Russian Roulette. Even with a highly skilled team, opinions and fatigue can occasionally lead to overlooked mistakes. Additionally, the pressure of other tasks can make code reviews seem necessary but frustrating.

Yet, can we truly afford to skip or rush this step? No, not without inviting bugs and bottlenecks down the road. Thankfully, technological advancements, such as AI code review tools, show us a better, more efficient way to review code without having to rely solely on the availability of a human reviewer.

Challenges of Code Reviews in Teams

Consider this scenario: You've created exceptional code, much like a perfectly blended smoothie, ready to delight users. However, before you can serve it, you'd like a team member to evaluate it. This step is crucial because, even when you put forth your best effort, some issues might go unnoticed. These issues can later evolve into significant problems, such as critical bugs, system crashes, or vulnerabilities. Now, imagine that this team member resides in a different time zone, perhaps asleep or preoccupied with other tasks. It's akin to attempting to share your smoothie at a party, where everyone struggles to find the right moment for a sip.

So, what's the solution? You could attempt to enforce a strict schedule for everyone or request team members to work during unconventional hours. However, this approach can lead to exhaustion and unhappiness. Instead, why not harness technology to address this challenge? This is where AI-powered code review tools come into play. They operate continuously, regardless of time zones, sleep patterns, or changing moods. They're consistently available to assess your code's quality without obstructing your project's progress.

The following sections will delve into how these AI platforms streamline code reviews, making them more manageable and remarkably efficient. Spoiler alert: Your perception of code quality and team productivity is about to undergo a transformation.

Why Manual Reviews Slow You Down: A Look at Productivity Metrics

In code reviews, problems can happen even when everyone works in the same place. Sometimes, teams just agree without really checking. People might not get along, causing delays and making things tense. Plus, even if we try really hard, some issues can slip by us and turn into big, expensive problems like bugs or system crashes. So, we need better ways to catch these problems early.

Let's look at some numbers because engineering managers really like facts and figures. Studies tell us that developers spend around 20-30% of their time doing code reviews. There's even a study here that shows our brains struggle to review more than about 400 lines of code at once, making it harder to spot mistakes.

We all know time is super important. It doesn't just impact how much money the project makes, but it also affects how much your team gets paid and, in the big picture, how well the company does overall. When a big chunk of your developers' time is used up reviewing code, it's not just a tech thing anymore – it's a big deal for the whole business.

Think about it this way: these hours aren't spent on making cool new stuff, resolving problems, or coming up with fresh ideas. Instead, they're used up carefully looking at code that's already there, trying to find mistakes, things that could work better, and stuff that doesn't fit. This is often where things slow down and work takes longer. While making sure the code is great is important, doing it manually uses up resources that could be used better elsewhere.

This isn't just about shipping faster—although who doesn't want to do that? It's also about optimizing your team's time so they can focus on what they do best: create remarkable software. If an AI code review tool can handle the initial pass, highlighting potential issues with the code, the developer can resolve initial feedback faster and your human experts can spend their time solving more complex, higher-level problems.

In the next section, we'll understand how AI-powered code reviewers offer a more efficient, context-aware, and timely alternative to the traditional approach. Because let's face it, it's time our methods evolved to match the pace of modern development cycles of rapid development and iteration.

AI-Powered Code Reviews: This Changes Everything

AI, or Artificial Intelligence, might sound like a trendy word, but in the world of reviewing computer code, it's not just a passing trend – it's a real game-changer. When we talk about AI in code review tools, we're not just talking about existing linters or static code analysis tools. Instead, we're referring to smart feedback that understands the context of your team's coding rules and the particular project you're working on.

But there's more to it. These AI-powered systems can chat with you, making the review process feel like a collaboration rather than a machine. This means you can ask questions, seek clarifications, and even discuss the best approaches, all in real time. It's like having your most experienced developer, who knows your code inside and out, ready for reviews 24/7.

Let's clarify a common misunderstanding: AI-based code reviewers are not the same as code generators. Code generators like GitHub Copilot assist you in writing code, while AI code reviewers are meant to assess and improve it. They are two related tools, each with its own unique features and advantages.

In summary, AI-powered code reviews provide faster and reliable feedback without sacrificing quality or depth. This enhances your team's productivity and allows you to push the boundaries of what's possible in your development process.
