Separating focused, creative work from interrupt-driven work is essential. Context switching between them is expensive.
On my engineering team we tried to collect all interrupt driven work together (triaging bug reports, working on deployments, production issues) and let it only bother one person. This is a sacrificial duty of your long-term productivity we all rotate each sprint (bug duty).
I find it easier to do interrupt-driven work when I'm full time in an interruptible context. I'd much rather be on-call for a week once every couple of months than be interrupted several times a day.
