Scrum only works if you need sprints, and you only need sprints if you have non-engineering stakeholders whose mandatory approval can only be attained in one meeting per sprint length.

Some large orgs really work like that, where the approval of one ham-fisted iron-gripped executive is deemed more important than hundreds of thousands of dollars of engineering talent going to waste. I don't think this is very effective but alright then.

Everybody else should just be using Kanban boards with periodic review.
