I feel like some people get a lot out of it, and others not so much. As in, if someone has the type of personality where they work best with lots of "heads-down" time on projects (and frankly many of the best engineers I know are like this), give them that space to do their best work without being interrupted by That One Person Who Always Comes Over to Chat. Most offices and even most orgs / teams have THAT DUDE. If you can't think of who it is, it might be you. Sometimes Dude has good ideas, but a lot of the time Dude just wastes time, and worst of all, wastes the time of others. Time that those other people could be spending Doing Work, but because Dude doesn't know when to can it, and because they're obligated to have their butts in their seats, they just make small talk while dying a little inside each day.
I've also seen people be incredibly productive because they can just walk over with a few people to another person and settle something in real-time. Doing that over email might take a day or two. Doing that over Slack could also probably work, and given how many people are in a meeting / out at lunch / OoO / whatever not at their desk, I'd say it's about a 50/50 chance that the unannounced walk-up actually works in person anyway.
Sometimes Dude is also one of the best engineers you know when he can just get some “heads down” time to himself, but when forced to be in an environment with many easy distractions, he acts like a kid on the playground. Or something.
I’ve been Dude in the past. Yesterday I was probably in danger of becoming Dude but for my general introversion and maturity. I walked around listening to James Brown instead. I think flexibility and a culture demonstrating proper time management and production would help. It’s important to socialize but without detracting from others. Yesterday, I just couldn’t sit or stay at my desk - I needed some air. In hindsight, I was pretty amped up from a meeting.
Absolutely. You could argue that a water cooler/coffee machine conversation is unlikely to be distracting as compared to interrupting people at their desk. If people are by the water cooler, kitchen, canteen, etc chances are they wanted to get away from their desks and would be open to engaging with others (even if bery briefly)
For what it's worth, I seem to recall reading that the most effective engineers are not necessarily the ones that (heads down) create the best solutions for some specific challenges, but those that know who is the best person to ask about (or task with) a specific problem. So, the Dude might be contributing quite a bit.
There's also the person who seems to not be contributing but who gently steers others towards a solution. Without this person, the team wouldn't work well, but looking in from the outside (or even from the inside sometimes), the person looks like they're doing very little.
