Scrum stifles innovation. Whenever someone tries to introduce scrum to my team I just link them to DHH's thoughts on the matter, he sums it up far better than I could hope to: https://nitter.net/dhh/status/1196856292683350016.
"Carving up the work to fit into these little, disjointed stories that can fit within a oppressively short two-week sprint is just soul crushing. Agile was supposed to be liberating us from process, but its current incarnation doubled down on its alienation. Software developers and designers aren't happy doing assembly line work. Calling that work "stories" is the great con of much modern agile process. A story without a beginning, a middle, or an end is a shitty one. It's more like just a scene, shot out of sequence."
