My last job was SAFe. When I started I was given Staff level title and had dreams of maybe moving into lead or management at some level. Once I saw the process I became completely unmotivated to go in that direction.

For them I understood some of the motivation. Hardware & equipment manufacturer, which involves scheduling complicated industrial processes for months/years out. So you need some semi-coherent vision of where things will be, so having a multiquarter waterfall-esque plan was going to be needed.

Not that any of that actually seemed to work.
