The Scrum Team identifies the most helpful changes to improve its effectiveness.
This is Scrum Guide update from November. Here is the reality 
In the old "management" we had change management with different methods such as: Lewin's Change Model, Kotter, Adkar just to mention few.
There is ongoing debate how to approach and lead the change in Agile environments to drive the transformations. Some say best is bottom up - engage the Scrum Teams, some say mix the bottom up with top down.
What's your opinion on how to lead the change when the Scrum Team is all but following Scrum values and pillars?
- closed
- not willing to experiment
- don't see the reason for the change
- say "it's good as it is no point changing"
- don't trust anything can change
- highly resistant
What one can do to actually overcome these and start implementing changes?
Should there be method used - anything you can think of and suggest?
How to create buy in for those who resist the most?
