That is not incompatible with adding some context in the "quick call invite". Even when I was working from the office, sometimes I would have to say no to someone who was reaching out to me or bumping into me in front of the water fountain because I was in the middle of something. In that case I would just ask to send me a message with some context and I would go back to him/her when I had more time to dedicate on that.
Maybe not incompatible but certainly diminished, the idea is you randomly stumble upon someone’s work or ideas who you wouldn’t have otherwise talked to if it needed to be scheduled, personally I think lunch in person is where this shines the most
Productivity doesn’t go down with fully remote work, but I think the kind of creativity that organically comes from ideas being constantly shared and discussed does
To be clear, I don’t think it’s always people’s job to be creative, and company’s should absolutely have roles for people who can work remotely who just join scheduled meetings and execute “the plan”
Innovation is about attention, not ideas. If you want to encourage that, you need to give folks a forum to share their ideas that they feel safe and supported. If your team is good at that in person at lunch, then having an “ideas” meeting with the folks who would be at lunch would work for that. If your team is bad at that, there’s likely some folks who don’t embrace the new ideas at your ideas forum and until you get them fixed, the folks with ideas aren’t going to bring them up for fear of looking dumb or whatever.
I’ve worked remotely and had a great time innovating, and I’ve been in person and had a terrible time innovating. It has always come back to giving folks a comfortable forum to share ideas and not rejecting them.
Many fully remote teams or companies host regular more laid back online events.
Where it doesn't work is in hybrid offices because people showing up at the office won't want to connect to some random videocall to do what they do all day every day.
