Bad management will turn any methodology into a bad experience. I also think scrum, and especially its implementations that I have been subjected to, could use improvement. I dislike the artificial time-constraints of the sprint, and the PI in SAFe. In my world, I wouldn't concern engineers with deadlines, but rather I'd have them work continuously, like in kanban. I think it eliminates overhead, and if velocity, and other such metrics are desired, management can conjure numbers out of thin air, just as they always did. Without sprints, there would be no need for planning either, but I'd hold refinement meetings regularly. What I'd do is break down the work into tasks and create a dependency structure, like the Critical Path Method in project management. I'd estimate in person-days, and that person would be a hypothetical normal teammate. Like, the best guy would do it in half that time, and a junior would take twice, even with hand-holding.
