“Best practices” have nothing to do with engineering. They are a marketing concept. They are a kind marketing better known as bullying.
In every case where you want to say “best practice” there is a better alternative, which is to say “practice.” The concept of best is never needed or warranted, because practices are not subject to rigorous testing and review.
I have been an independent consultant and trainer since 1999 and not once have I taught or recommended a best practice.
I do have many opinions. I call them: opinions. I think my opinions are the best, but I can’t think of any reason that anyone else beyond my wife and dog should think so.
