I have experienced it both as part of IT emergency response, as well as when cooking with (a very small subset) other people. As long as everyone is "on the same wavelength" (I am sorry, I cannot quantify that better), it is basically effortless. You need someone to chop onions, and a few minutes later, they're just there. You sense that someone needs a filleting knife (they're just about to place a fish on a cutting board, or something similar that signals "this is the next tool needed") and you're close to it, so you make sure it is there for them (handle first, of course). It is a very similar feeling to a well-integrated infantry unit making an entry into a presumed-hostile building, minus all the adrenaline.
