DevOps is a term that came around 10 years ago evolving from something like "Agile Infrastructure" and "Agile Systems Administration". The idea is to create a culture that brakes the barriers between devs and ops (it doesn't really matter how) in order to be "MORE" agile.
Those two things are tightly connected and sometimes it's actually hard to differentiate between one or another. Your team is good at DevOps only if the "ops" part is collaborating with the "dev" in order to satisfy your customers with continuous delivering of high value and quality software.
That's my point of view and I'd love to read some respectful disagreements : )
