The purpose of this request for proposal (RFP) is to identify vendors who can dedicate an estimated 40-80 hours per month for 24 months on an ad hoc basis to develop a new data management system and/or develop, refactor, and maintain one of the National Democratic Institute's (NDI) existing data management systems (Apollo, Foresight, or Magnifier) that conform to NDI best practices. It is expected that all databases would be comprised of five core modules as outlined in the Functional Requirements document (see Annex A) and that each module would be interoperable with one another.
