I find companies getting lost in their Agile transformation journey making their old habits creep in by enforcing processes, metrics, structure that tend to add bloat to the agile delivery mindset. This cannot be taught but has to be in the company culture and DNA. What have you found in your experience are best practices/tools/techniques that would remind teams of this core guiding principle? I also believe Agile and DevOps are 2 sides of the same coin and while you might be good at one of the Agile SCRUM-based (scaled or otherwise) frameworks like SAFE, LeSS etc. if you are unable to automate your delivery to the target, you are back to being bottlenecked from being agile.
The entire book is about going back the basic roots of Agile as was envisioned by at least some of the original 17 back in 2001. See my reply here: https://coderanch.com/t/730488/engineering/Clean-agile-scrum-dead#3398646 -- I think it's relevant to what you're asking as well, particularly the part about the Circle of Life and not forgetting about the technical practices that are essential for agility.
