My Agile is better than your Agile.
Nah nah, no it's not.
Yes it is!
To the point that eventually someone says, "Well, we're beyond Agile anyway. It's so yesterday."
To which I ask, "What part of Agile are we beyond?" If it's dogma, immutable bias, or canned solutions, I say good riddance for a' that! (with apologies to Robert Burns). They weren't consistent with Agile in any case.
Agile, in the Manifesto for Agile Software Development sense, is and always has been about a mindset. That mindset is expressed through 4 value statements and 12 principles. If you haven't checked them out in a while, go ahead and refresh your memory (http://agilemanifesto.org). I'll wait...
Good, you're back. As you may have noted, as expressed in the "Manifesto", Agile is not a methodology or a specific set of practices. It's not that simple, and we haven't even begun to get it even slightly right in most implementations. Face it. There's a lot of bad Agile out there.
So let's stop these Agile 2.0, Agile 3.0, Agile n+1.0 escalations and brash, sword-rattling posturing about abandoning Agile for the next bright shiny object and get on with it. There's still a lot of work to do.
