Against Best Practices

I think the rejection is too strong in this article. The idea of, “best practices,” comes from an established Body of Knowledge. There is one published for software development called the SoftWare Engineering Body of Knowledge or SWEBOK; published by the IEEE.

The author seems to be arguing for nuance: that these “laws,” require context and shouldn’t be applied blindly. I agree.

However they shouldn’t be rejected out of hand either and people recommending them aren’t idiots.

Update: one problem with “best practices,” that I think the article might have unwittingly implied is that most software developers aren’t aware of SWEBOK and are repeating maxims and aphorisms they heard from others. Software development is often powered by folklore and hand waving.

I think it is best to strongly reject the idea "best practices will always benefit you".

Most best practices that I have been told about were low local maxima at best, and very harmful at worst.

If someone quotes a best practice to you and can't cite a convincing "why", you should immediately reject it.

It might still be a good idea, but you shouldn't seriously consider it until you hear an actually convincing reason (not a "just so" explanation that skips several steps).

This matches my experience, though sometimes they indeed will be helpful, at least after some consideration.

In certain environments this will get you labeled someone who doesn't want to create quality software, because obviously best practices will lead to good code and not wanting to follow those practices or questioning them means that you don't have enough experience or something. Ergo, you should just apply SOLID and DRY everywhere, even if it becomes more or less a cargo cult. Not that I agree with the idea, but that way of thinking is prevalent.

(not that I agree with that, people just have that mindset sometimes)
