Is a project multidisciplinary if only one unit is being enhanced, but the project involves faculty from other units to assist in the enhancement of the submitting unit?

The previous Multi competition was designed to give a competitive space to projects that fell in between disciplines because two departments were working together. Business and Computer Science might actually be putting together a shared lab that was a huge boost to each department but fell out of the normal scope of the Business or Computer Sci competitions, and might be dismissed. Now we have designed a review that builds that into a single competition.
