To your point, it’s probably best to never 100% agree.
Seriously though: I’m very comfortable with the term ‘deviation’. Deviation is an essential facet of innovation. I’m reminded of one of Zappa’s infamous quotes: “Without deviation from the norm, progress is not possible.”
Having said that, I also appreciate the end note in the Scrum Guide where the authors simply say: “Scrum is immutable.”
How to reconcile these two contrasting ideas?
It’s important to be reminded that the authors of Scrum are not saying, “don’t deviate”. Rather, they’re politely asking us to respect the definition of Scrum as if to say, “If the way you work resembles this definition, then call your work Scrum; if the way you work does not resemble this definition, call it something else. If you want the results of Scrum, use Scrum. If you have discovered a deviation from Scrum which produces better results…great!”
I’m a huge advocate of Scrum. I teach it. I practice it. I believe it has helped thousands of organizations to improve. And I assert it ought to be a goal for some – that is, until they have uncovered every possible iota of wisdom from it and then they’d best deviate from it in the pursuit of even greater adaptability.
Good chat. Thanks!
