Small team with a largely overlapping shared knowledge and attitudes.

Which is not to say it isn't really nice, but I think the chances of it happening are in some way inversely proportional to the number of people involved. It's probably not linear either.

I haven't thought about it in years but my very first pc support traineeship ( 25 years ago!! ) had aspects of this. There was so much shared context for us both that we often left it out, much to the bemusement of anyone else listening.

"Hey, remember we need ", "yeah", "oh and can you pick up", "already did its over there", "oh cool ok can you", "sure, probably after lunch"

It was FUN. But you just can't do it with much more than 2 or 3 people.
