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.
Yeah, you can make fewer people do more jobs.
You can make your team better at more kinds of technology. If management sees that as an opportunity to cut people then that’s management being dumb. But DevOps is still fundamentally a good thing.
