Here is how I define a Best Practice:
  • Best Practice -a practice that is good(but not necessarily the best) in almost all contexts and almost all team situations. This does not mean it is truly the "best" practice in all situations, nor is it necessarily the best practice for your team. The notion of a "Best Practice" in any industry or context is a Unicorn because there is no such thing, so I define it differently here to mean what most people think it means -- a good practice in almost all contexts. If someone can convey my definition in a term that is just as easy to understand as "Best Practice," then I'm all ears. Some have suggested "Great Practice" or "Great Practice in Context"
