Code review is, hands down, one of the most fundamental best practices a software shop can employ to produce better software. A good code review practice can shed light on design problems, improve the readability of the code, and spread knowledge throughout a team. It also helps you find bugs early (when it costs less to fix them).
Code reviews sound like a gift from the heavens, right? While far from being a panacea, I’d say they are a spectacular tool to ensure software quality—when done correctly. And that, of course, is the tricky part. It doesn’t take much for a code review practice to go downhill. If you’ve been a developer for at least a few years, then I’d bet you have your share of scary stories to tell.
But that’s not what we’re here to talk about today. Forget the truly horrific stories—toxic workplaces and the like. Today we’re going to cover inefficiency in code reviews. Or, more precisely, we’ll offer you tips on how you can avoid it.
So, without further ado, let’s get to it: four tips that will help you when preparing to implement a code review practice in your software shop.
