There was a time I was running a 10+ team and was executing scrum by the book, not really understanding much of it at start. Meetings felt weird and generally it was very intense time. But after some time a few things clicked in my head: I could plan with some certainty without bothering people, and execution was falling between min/max planned capacity, everyone was aware of pretty much everything, even in 'other places' where they were not actively contributing, everyone learned to estimate their work based on complexity. And above all, after leaving the place and working in a few different shops, when I look at the code quality produced in that place I'm still impressed (not brownnosing myself, really). We executed ~50 2-weekly sprints, I miss that time.
