Even when I was still working in an office, coordinating incidents through a Google Hangout and a Google Doc to keep rough notes was the way to go. Want to show something? Share screen. Want to talk in private? Jump into a private hangout. Want to jot down some thoughts/unfinished ideas? Throw them into the document (the Hangout chat was pretty useless because people joining later couldn't scroll back) or into the dedicated Slack channel for the incident.
If anything, incidents have become much easier to coordinate thanks to all the tooling that we now have - though that requires an active incident commander (who also makes sure that Deanna, Deepak, and Sylvain are not just waiting, but investigating other possibilities). Fortunately, someone has written an article on how to become a better incident commander :)
I absolutely wouldn't want that to be my daily life, but while we needed it, it worked. More than that, it was better than being in an office- when I wasn't needed or wanted to crack down on something without distraction, it was super easy to get away from the noise. When I saw a bunch of avatars in a meeting room, I could pop in without causing a disturbance to see if it was about anything I could pitch in on.
Thankfully, we're long past that point, and it became a lot less useful to the point that our team stopped using it not long after we were out of crunch mode.
I'm speaking as someone who worked full time doing nothing but incident management at a F500 for a couple of years before the pandemic. The incident team for literally every single response I ran in that time was effectively remote; most weren't in the same building as me, probably weren't in the same time zone as me, and it wasn't unusual for them to be on a different hemisphere entirely.
Physical proximity to one another has absolutely nothing to do with the ability to work an incident. Effective communication is vital, but this isn't uncharted territory. Large organizations have been doing this effectively for a very long time before the entire in office/remote debate ever became a popular controversy.
Or you might be in a different building, in a different city, or different country halfway across the world.
Or it might just be 4 AM for everyone, and there might be no time to go into the office, even if you all normally sit together.
All of these are real things I’ve seen and not hypothetical in the least.
A good whiteboard software with incident exec summary, chat history, and "useful links" from troubleshooting chatter is needed.
Maybe I've benefitted from having my own team colocated during an outage. But it has rarely been useful to have a cross-functional outage team in the same room when doing log research.
If Oscar wants your ideas, maybe he should be able to ask for them, or accept a spitball-session.
Whatever you conclude from his facial expression, maybe he can verbalise that himself, unambiguously if relevant; instead of frantic speculation based on first impressions.
Completely different, no office environment solves this problem.
