Two thoughts:

> "Way of work should be defined at a team level by its people, not by the company."

OP delivers that like a surprise, but isn't that the single core defining tenet of Agile? I thought it was.

> Sprint Planning — as simple as it seems, a long session (up to 4 hours)..

My big insight is, painful sprint planning is a result of painful deploys. Once you accomplish real CICD, you can just dispense with sprints and sprint planning entirely.

I'm not sure if that's something most people would agree with or not so I won't belabor it unless someone argues, but I can go on at length about that...
