When I started, I was really bothered by the fact that everything took so long. I had joined from a startup where there was time/financial pressure. Everything needed to be done now, and there was incentive to get it done.
The cloud provider was the complete opposite. Everything was slow. Things that should take a day took a week, things that took a week took a month. I rationalized it that there were more checks in place, more i's to dot, more t's to cross.
But in hindsight, it was the domino effect of Parkinson's law in play. The cloud provider had enough money to keep paying everyone in perpetuity; that removes financial constraints. Time constraints could be explained away. So things just got done whenever they got done. The knock on effect of this is that when you depended on other teams, they got around to their external responsibilities whenever, that then slows you if you depended on them.
The larger organization accounts for this by expanding timelines (because what else are directors/vp's/etc to do... they're powerless to actually implement), which are then just filed with more waste.
