Best practices? I'm not so sure.

I'll be delivering a webinar this week that has the words "Best Practices" in the presentation title. As I've been preparing, it has really struck me how my definition of a best practice is not the traditional IT definition. Wikipedia says

A best practice is a method or technique that has consistently shown results superior to those achieved with other means, and that is used as a benchmark.

OK. That sounds reasonable, right? So, what's my problem? Well, I think that if this definition is the traditionally accepted standard definition, there's something missing. What about context? I suppose you could infer that a specific context is implied for any best practice, but the inference isn't enough. An unfortunate side effect the label "best practice" has when it is attached to any method or technique is that it makes people blind to the context in which the practice should/could be applied. Can you think of any examples where a practice that is "best" in one context is questionable within another? Sure you can (feel free to share yours in the comments!). But, so often, many people will take a best practice at face value without considering the context of their own situation.

I think a best practice is really a contextual practice. I'm borrowing this term from Eric Ries, author of The Lean Startup. Ries writes that we should strive to understand the context which we find ourselves in, and then apply the practice which is best within that context. I couldn't agree more. It's not about blindly following steps or guidelines that may, or may not, be applicable and particularly useful in your situation. It's about understanding. You've got to understand your situation and take steps that make sense in that context. Not simply take steps that worked for some other person, in some other context, at some other time, just because it is labeled as a "best practice".

My goal for my webinar's list of "best practices" is to offer ways to gain understanding and clarify the context of your specific situation when developing SQL. With a clearer understanding and proper context, you can have confidence to make the right choices that lead to optimal results. Come join me for the webinar and see if I succeed!
