Don’t be a time thief. More precisely, if a decision has been made let it stay made.
This tip won’t necessarily change your personal output a whole lot, although you will have more time for your own work if you don’t waste it rehashing old decisions, but it will be fantastic for your team’s productivity. Being a better programmer isn’t just about how much you personally get done, it’s also about how much your whole team gets done. If you make your team better then congrats, you’re a better developer!
You will have to deal with decisions you don’t like as a developer. I’m not saying that’s a good time, but that’s not just life as a developer, it’s life in general. You can either accept those decisions like a grownup, or you can waste everyone’s time by fighting the same battles over and over.
Now, if something has substantially changed, like a new tool has been released or there has been an announcement that an open source library is no longer being actively developed, then it may make sense to reopen a closed discussion. But if you just don’t like the decision, you’re wasting everyone’s time. Even if you are technically right it’s generally faster to rework your codebase to recover from a decision that didn’t pan out than to have the same meeting over and over. It’s not just about the single decision, it’s about how you use your time.
It’s also about morale. It’s incredibly frustrating when you have meeting after meeting and finally decide something, only to have someone drag it all back up again a few weeks later. What was the point of all the earlier meetings if a decision that’s been made doesn’t stay made? If you want people to stop bothering to share their opinions, that’s the way to do it. Like I said last time, you have to be open to the idea that you could be wrong. You need your team’s ideas to make the best decision you can, and you can’t possibly get anyone’s real ideas when you convince them that it doesn’t matter what they say.
Arguing about things that are purely a matter of opinion is time-theft too. Curly brace on the same line as the method declaration vs the next line? tabs vs spaces? line width? No professionals bother to argue about that at work (the bar is a different story, however :) ), we pick a coding standard, set our IDEs to autoformat our code correctly and move on with our lives. Some arguments simply are not worth the time it takes to have them.
Speaking of arguments that have been had over and over and are a profound waste of everyone’s time, biology simply does not and never has explained the lack of women in computer science. We seem to drag this argument back up every few years in tech and every time it’s as foolish as it was last time. Google bro is simply the latest to waste thousands of hours of everyone’s time with ideas that have been debunked over and over. A grownup, not to mention a competent developer, would never have wasted everyone’s time with an argument that’s been hashed out dozens if not hundreds of times already. You simply can’t have someone like that on your team if you ever want to get anything done – even a competent developer, which Google bro certainly is not, couldn’t offset the collective productivity lost to rehashing well understood decisions over and over.
It’s perfectly normal to want to undo a decision you don’t like, just like it’s perfectly normal to want to stay in bed on a cold, wet morning and it’s perfectly normal to want to buy lunch and skip packing one. Wanting, however, is different from doing if you’re a grownup and you just can’t be a good developer without being a grownup. Even a lone hobbyist faces frustration and disappointment, you can either let those stop you in your tracks or you can set them down and make yourself useful.
