Code reviews can increase in-team knowledge sharing and improve code quality.
However, in some teams, this process can be very time consuming and tiring.
What can be done to make these processes more efficient❓

Code reviews enhance knowledge sharing and code quality within teams, but they can sometimes be time-consuming and exhausting. Exploring ways to make this process more efficient is crucial.

Do you think code reviews are really necessary❓

Aside from the obvious fact that it helps with bug detection and quality assurance, it also promotes knowledge sharing within the team. Less experienced developers can learn from more experienced developers.

Yes, code reviews can be time consuming but it is part of the product development.
if we agreed to bypass the code review and push to prod, it will make us lose more time debugging for same silly issues

I agree with both previous comments, code reviews are essential for:
<ol>
<li>Catching a lot of bugs (not all) before they get merged and cause more money/pain/time when you’re forced to fix them later</li>
<li>Sharing knowledge across the team. In a busy project you may never see any details of an entire aspect of the project apart from the code reviews.</li>
<li>It helps you learn not only the project but your teammates, their coding style, the approaches they use, the conventions they like etc. It exposes you to solutions and approaches that perhaps you didn’t expect and it either reinforces why you shouldn’t do it that way or teaches you a better way you hadn’t seen before.</li>
<li>Collaboration and communication. Everyone makes mistakes in coding. It gives more junior members the chance to critique a senior’s code and discuss things with them in detail when perhaps they might not feel comfortable just approaching them without the code review process to push them into it. Conversely, it gives seniors (who might not be comfortable teaching) a formal process through which they can explain and give guidance making it easier to start conversations they might hesitate to just bring up normally.</li>
</ol>
If you want efficient code reviews then its up to the team to sit down and discuss what they want from code reviews, what they don’t want and decide the best format to do that. Maybe that means your team does things slightly differently. Trust more than one person to do the reviews rather than a bottleneck of one senior getting flooded with backed up pull requests.
I’ve seen terrible approaches to code reviews and I’ve seen great ones. In the great ones it was always because the team took ownership and talked through what they wanted and then did it and reviewed it each iteration until it became smooth.

It’s like writing tests. Yes, it’s time consuming but very important for the quality of the product.

I just missed a potential bug in UAT because I trusted the ‘test case’ and did not review the code carefully.
So yes, code review is a must. We even have checklist to do this kind of thing.
