The core mission of the Office of Management and Budget (OMB) is to serve the President in implementing his vision across the Executive Branch. OMB is the largest component of the EOP. 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. Organizationally, OMB has offices devoted to the development and execution of the Federal Budget, various government-wide management portfolios, and OMB-wide functional responsibilities.
