Not discounting this, but i Free-form 1:1's always have an aura of being more "improvisational" and in the moment. Good 1:1's are supposed to be semi-structured (ie not 'free form'). A shared journal, a retro exercise, etc. I have not had the experience that these build trust. Good team work, and delivering high quality work towards a common goal do that. You popping by for a 3 minute conversation in ear shot of 5 other people trying to do their work doesn't.
It may FEEL like it because those people chatting get energy from it. But it doesn't. If you need energy from people like this it's 100% a good idea. Go nuts. Personally I think people over index on this because they have no idea how to structure async team comms.
– Videos
– Longform content
– Team agreements to respond to things async without x-hours
– Team collaboration spaces
– Good sprint ceremonies like refinement
– Team QA-type exercises
Ad hoc conversations also contribute immensely to what I call "comms debt". The jolt of energy you get from water cooler talk last 3 minutes, and excluded anyone not in direct proximity. If the best idea was in the head of somebody 3 rooms away you have no way of knowing it. Add dozens of these micro-interactions throughout the day and it's a recipe for comms breakdown and kliqish behaviour.
I see this a lot in User Research. Let's "get out of the building" and talk to people. A good idea in practice, but without actual goals or hypothesis product leaders mistake the first 5 opinions they collected as fact — often cherry picking sound bytes that fit right in with their own biases (and I've seen this A LOT in older leaders). This is mistaken as research. But they love it because it has that face to face energy. The feeling makes it right, regardless of the evidence.
Trust in a team is based on good communication — and an agreement on what you expect from it. If someone posts a video to Slack do people respond? Do you have ceremonies to build togetherness and understanding? All of these things are somewhat easier when you just have to deal with Zoom logistics.
Anyone who has to clean up and index the deluge of Design Sprint whiteboard stickies knows what I'm talking about. Put that shit in Miro, thanks.
