Such a perfect match to my own conundrum about the discipline of software development practices we so often call Agile.
It's hard, because industry calls on us for names to indicate proficiency. But for me this is a whole set of common sense ways to do better. And I've been at it a very long time.
So when people ask "but are you a Certified Scrum Master?" it's hard to answer. I tend to say things along the lines of "No. BUT! I predate that term and know all about the practices and definitions that make it happen." But that doesn't fit into their box. Even though it means I'll bring more actual agility to the discussion than any one set of practicies, like Scrum.
Let's aim for Agility, and use the Agile Manifesto values and principles as that guideline.
