banyan model
n.— «He proposes that work groups whose members are widely dispersed but need to have high levels of coordination—say, a computer security team protecting a global bank—do not have to assemble everyone in one room to reap the same benefit. Instead, he suggests a “banyan model,” after the Asian tree that puts down roots from its branches.» —“E-Mail Is Easy to Write (and to Misread)” by Daniel Goleman New York Times Oct. 7, 2007.
