Office of Federal Procurement Policy’s (OFPP) memorandum, dated September 29, 2011, Development, Review and Approval of Business Cases for Certain Interagency and Agency-Specific Acquisitions, outlines required elements of business case analysis as well as a process for developing, reviewing, and approving business cases to support the establishment and renewal of government-wide acquisition contracts (GWACs), certain multi-agency contracts, certain agency-specific contracts, or agency-specific blanket purchase agreement (BPA). Agency-specific vehicles are either indefinite-delivery, indefinite quantity contracts or blanket purchase agreements intended for the use of your contracting activity, the Department of Energy, or another Federal Agency.
