The Administrator shall provide overall direction of procurement policy and leadership in the development of procurement systems of the executive agencies.

To the extent that the Administrator considers appropriate in carrying out the policies and functions set forth in this division, and with due regard for applicable laws and the program activities of the executive agencies, the Administrator may prescribe Government-wide procurement policies. The policies shall be implemented in a single Government-wide procurement regulation called the Federal Acquisition Regulation.

In any instance in which the Administrator determines that the Department of Defense, the National Aeronautics and Space Administration, and the General Services Administration are unable to agree on or fail to issue Government-wide regulations, procedures, and forms in a timely manner, including regulations, procedures, and forms necessary to implement prescribed policy the Administrator initiates under subsection (b), the Administrator, with due regard for applicable laws and the program activities of the executive agencies and consistent with the policies and functions set forth in this division, shall prescribe Government-wide regulations, procedures, and forms which executive agencies shall follow in procuring items listed in subsection (c)(1).

The Administrator, with the concurrence of the Director of the Office of Management and Budget, and with consultation with the head of the agency concerned, may deny the promulgation of or rescind any Government-wide regulation or final rule or regulation of any executive agency relating to procurement if the Administrator determines that the rule or regulation is inconsistent with any policies, regulations, or procedures issued pursuant to subsection (b).
