The Federal Acquisition Regulation (FAR) is the basic US Federal Government document which specifically states how all federal agencies will conduct procurement and contract administration. First published in 1984, it promulgates current laws, Congressional policy, and executive agency mandates as they pertain to federal contracting.
Changes and revisions to the FAR are developed by one of two standing committees; the Civilian Agency Acquisition Council (CAAC) and the Defense Acquisition Regulatory Council (DAC). Changes to the FAR are promulgated by the Federal Acquisition Circulars (FACs) which are published periodically and contain updated pages of the FAR.
