> the Scrum proponents will rush in and tell me that we were doing it wrong The "no true scrumsman" fallacy at work.
It's not a "no true Scotsman" (scrumsman :)) if the counterexample is in fact not a Scotsman. Whether it is or isn't depends on your feelings on scrum, but it's not a fallacy to try to defend the initial definition before it was co-opted by anyone with an Agile cert. "Hammers suck at driving nails." "You're holding a rubber mallet." "No true Scotsman!"
Every bad Scrum/Agile situation I've been in has orchestrated by people who were convinced they were doing it "the right way"
Every defense I've read has been from other people who weren't there who insist that it must be "the wrong way".
If you define the "right way" such that it can only be good, then you conveniently dismiss all of the negative criticisms at once. Yet in the real world, there appear to be a lot of us stuck in companies who think they're doing it by the book but it's still not working out.
