Ad Hoc Work Groups - Ordeal?

I'm a big believer of things that you do regularly in your creative process, your work and your life should be smooth and easy and low friction. To me, something like people coming together to form a work group of some kind is a really common frequent activity. And it also doesn't have super clear boundaries. But I often feel like the ordeal of bringing someone into space to work with them does not reflect the more fluid nature of the way we collaborate today.
