The core mission of OMB is to serve the President of the United States in implementing his vision across the Executive Branch. OMB is the largest component of the Executive Office of the President. It reports directly to the President and helps a wide range of executive departments and agencies across the Federal Government to implement the commitments and priorities of the President.
OMB carries out its mission through five main functions across executive departments and agencies:
1. Budget development and execution;
2. Management, including oversight of agency performance, procurement, financial management, and information technology;
4. Clearance and coordination of legislative and other materials, including agency testimony, legislative proposals, and other communications with Congress, and coordination of other Presidential actions.
5. Clearance of Presidential Executive Orders and memoranda to agency heads prior to their issuance.
