The Department of Interior purchased licenses for the American Management System's Federal Financial System in 1987. Subsequently, the Washington Administrative Service Center and the Denver Administrative Service Center implemented the system throughout the DOI bureaus. The WASC and DASC were internal service centers of the Department of Interior at bureau level. Starting in 1988, the WASC extended its support to non-DOI federal agencies in the implementation and operation of FFS via cross-servicing agreements. In 1999, the WASC began implementing CGI Federal's (formerly American Management System) Momentum Financials in non-DOI federal agencies. In 1999, the WASC and the DASC were merged to form the National Business Center. In 2003, the organization began offering Oracle Federal Financials to non-DOI customers. Therefore, the answer to this question is that the Interior Business Center, a result of the merged DOI service centers, has been providing financial services to government agencies for over 20 years.
