It's funny, the root of the idea is that Agile allows teams to change how they are doing things midstream so we can constantly improve. But I have never met a scrum master or PM who has both the authority and the desire to advocate for changing how work is done. So all it ends up being in practice is a series of rituals that people sleepwalk through.
Dilbert captured it best: "Our boss can't judge the quality of our work, but he knows when it's late". For everybody doing programming work, there are ten people tasked with making sure it's done by the "due date", whether there's any value in that due date or not.
