My impression from some of my colleagues is that Multi actually means Two.
I think that when a few engineers think of multi-disciplinary teams, they think about crossing the boundaries between disciplines between structural engineering and building services engineering. I think this might be because of the way that they have been brought up within the confines of one discipline and not really introduced to the concept of multi-disciplinary teams until employment, or select employment.
I percieve multi-disciplinary teams to encompass anything and everything outside of one particular discipline.
So multi-disciplinary can mean two, but it could also just as easily mean ten, twenty or even one hundred very different disciplines.
