Scrum is an agile framework that, if applied properly, can boost the efficiency of teamwork. It is known to be versatile enough, so it could be applied in basically any sort of productive teamwork, even beyond IT (e.g. bakeries, government organizations, etc.)
However, I’ve never ever seen it being used anywhere else other than in software development, therefore I’ve always been curious if Scrum is actually being used outside of IT somewhere.
Line cooking is essentially scrum. Each ticket is a story. They are added to the backlog as they come in and added to the sprint when you start cooking.
