Would a proposal need to fall within two disciplines as defined in the RFP eligibility table to be considered multidisciplinary?

For a proposal to be Multi it needs to: a) be submitted by a department that is based in an eligible discipline b) the submitting department must receive equal or greater benefit from the project than the other participating departments and c) at least one other department must benefit, it must present its own mission statement and state its case for why the project fits the priorities described in that statement, and it must have faculty involved that have actual roles. The partnering departments do not have to be based in eligible disciplines.
