In ops, I think sprints work uniquely terribly. Lots of super urgent tasks come up in a normal workday that aren't always captured in the workload or capacity planning, and some times are much more interrupt driven than others, leading to similar issues.
Another issue I had with it, it did not really encourage me to be super productive . Like, I took on 16 story points this sprint, finished them all in a week, what possible incentive do I have to take something off the backlog and squeeze it into this sprint when my teammates (some of whom are paid more than me) are doing half of the "points" I am? It creates tension where I don't think any is needed. To make things worse, the system is easily gamed.
Another thing is I think it created way way more meetings than was needed.
