Pretty common in “DevOps” teams, in my experience. Some people are working on some autoscaling CI runner server initiative, some are working on writing code, some are fixing issues in CI pipelines, some are hardening the security of kubernetes clusters, etc. Their goals are completely unrelated to the others but is all work that falls under their team’s umbrella, and needs doing.
Equally common in operations roles for the same reasons. Lots of servers and networking gear. You might be changing failed hard drives in a RAID array while someone else is patching servers while somebody else is upgrading some 20 year old Cisco firewall. None of these three people rely on the work the other is doing. Especially if they’re working in different server cabinets.
