Is it really the best just because its the most common?
I cannot count the number of times I’ve heard someone ask these two questions—
- What are other people doing?
- What is the best common practice?
While these questions have always bothered me, I could never really put my finger on why. I ran across a journal article recently that helped me understand a bit better. The root of the problem is this—what does best common mean, and how can following the best common produce a set of actions you can be confident will solve your problem?
Bellman and Oorschot say best common practice can mean this is widely implemented. The thinking seems to run something like this: the crowd’s collective wisdom will probably be better than my thinking… more sets of eyes will make for wiser or better decisions. Anyone who has studied the madness of crowds will immediately recognize the folly of this kind of state. Just because a lot of people agree it’s a good idea to jump off a cliff does not mean it is, in fact, a good idea to jump off a cliff.
Perhaps it means something closer to this is no worse than our competitors. If that’s the meaning, though, it’s a pretty cynical result. It’s saying, “I don’t mind condemning myself to mediocrity so long as I see everyone else doing the same thing.” It doesn’t sound like much of a way to grow a business.
The authors do provide their definition—
For a given desired outcome, a “best practice” is a means intended to achieve that outcome, and that is considered to be at least as “good” as the best of other broadly considered means to achieve that same outcome.
The thinking seems to run something like this—it’s likely that everyone else has tried many different ways of doing this; that they have all settled on doing this, this way, means all those other methods are probably not as good as this one for some reason.
Does this work? There’s no way to tell without further investigation. How many of the other folks doing “this” spent serious time trying alternatives, and how many just decided the cheapest way was the best no matter how poor the result might be? In fact, how can we know what the results of doing things “this way” have in all those other networks? Where would we find this kind of information?
In the end, I can’t ever make much sense out of the question, “what is everyone else doing?” Discovering what everyone else is doing might help me eliminate possibilities (that didn’t work for them, so I certainly don’t want to try it), or it might help me understand the positive and negative attributes of a given solution. Still, I don’t understand why “common” should infer “best.”
The best solution for this situation is simply going to be the best solution. Feel free to draw on many sources, but don’t let other people determine what you should be doing.
